No prob. There are a few different ways to wire them, so it's a little of dealer's choice. I did it the way they recommended, and I'm happy with the results so far.

Tagging in to watch the build.

I will ask this as well.... Why staggered wheel sizes but same size tire @ all 4 corners? Is your plan to break the tires down off the wheels for rotation?

At first, I was going to go with a true square setup, but the wheels are hub-centric, and the hubs front-to-back are different sizes. So almost immediately I realized that I'd have unique front and rears, even if they were the same size and backspacing.

Once I realized that I opted to go with a concave design on the rears, and since there was the room I also opted to go with a wider wheel to allow for a wider drag tire (like a 345) in the future if I ever wanted it.

The reason I didn't go with wider rear tires, to begin with, is one, I wanted to feel what a square setup did for stability and handling, and two, going above a 315 also meant going down a size in sidewall (from 35 to 30), and I didn't want to do that for my daily driving tires.

Did some wheel and tire measuring today. Looks like I'm going to squeeze a 315/35R20 front and rear.

Thanks to MCB for letting me borrow their wheel measuring tool, and thank you to GoMobileTires for coming out with different sizes to test out!

I'll be posting a video of the mounting/balance process in the future.

Now I just have to decide on the Forgeline wheels I want

Wheels ordered!

Going with the Forgeline ML3C in a pearl grey. I really like how they look on the site, so just going with that.

20x11 fronts with a 6.75" BS, 20x12 rears with a 7.75" BS

Nice video, excited to see some of these things come to life. I'm at a crossroads right now about radio/backup camera. I like your ideas. Unfortunately I am at a pace where I don't have much time left to decide so I need to figure it out quick. I want a backup camera. And am trying to figure out if I should either do a rear view mirror camera and keep the stock dash look, or install a double din radio and use that for rear view camera.... I am very interested in your GM rear camera mirror....

Keep up the good work!

[siggyfreud]

It's not cheap, but this is what I'm going with I think. I recall the Ring brothers mentioning this company makes the OEM unit for the Bolt and other Chevy vehicles with the trick mirror. But this is less of a backup camera solution and more of a crystal clear rearview solution. It's the same mirror perspective, just without reflection/obstruction by objects in the cab.

It probably won't be within your timeline, but I'd really love to get a new printer and 3d print a solution for that bed light/3rd brake light/camera holder. But the 3d printer I want is about 5-6k, so that will be awhile. Right now that money is going to wheels so I can drive the darn thing again.

Hey all,

Minor update, but no video this time. Got the wheels in, and tires mounted! I ended up going with 20x11" front, 20x12 rear, with 315/35R20 on all 4 corners. 315 was about the widest I could find that still had a bigger sidewall profile. I also wanted to run a square setup, and 315 seems about the max front width.

As it is I get rubbing at full turn on the LCA's shock mount. That will go away when I swap to new front suspension though. I'm considering Ridetechs strong-arms with Shockwaves at the moment.

Drives and brakes very nice so far. Going through the bedding process, which requires 4-5 days of just regular driving before baking in the rotors, then pads. I need to adjust my brake light switch though, as it requires much less travel to stop, so my brake lights aren't even engaging at the moment.

At some point I'm also going to shift my brake pedal back so it's even with the gas. I may wait until I get a plasma table down the road, then I'll cut one out in the shape I want.

Here are some photos:

Love the wheels!!

[LakeAnna]

Truck looks good man!

[siggyfreud]

Thank you both!

[cornerstone]

Wowzers! 315s all the way round

At your front door tire and wheel delivery? Love it!

[siggyfreud]

Yup, the 315's fit rather well, aside from rubbing the lower shock mount on the LCA at full turn. That will go away when I switch to new control arms and suspension in the front. I will say the truck feels way more planted so far driving on these tires. With the brakes and steadiness on the road it's way more of a pleasure. Once the new suspension gets in it'll be even better.

The wheels I bought through Matt's Classic bowties, and they shipped right from Forgeline to my door. The tires I got through a company called GoMobileTires. They're in like 4-5 different locations across the US. The owner is up here. He came out a few months back and brought 3 different tire sizes to try out with a wheel fitment tool I borrowed, and then came back when it was time to mount them.

The nice thing is that their tools don't really touch the wheel at all. So unlike a lot of tire shops that use those pry bars and whatnot, your wheels don't get touched and won't get scratched up with their process. They mount them, air them up, and balance them right there in the van. Takes about an hour, their tire prices are on par with discount tire and amazon, and they charge $150 for the service and to take away old tires, if you have any. For me it was totally worth it as opposed to going to a shop.

I highly recommend them.

I like the stance and the wheel widths.
Question on the rear tire fitment.
How wide are your wheel wells?
Has the axle been shortened?
Is it a 72 axle?
If you can’t tell I’m researching

[siggyfreud]

Hey there.

I'll have to measure the wheel wells, I forget what the measurements are on them.

Axle has not been shortened. Yeah it's a 70.5+ axle, so wider than the previous incarnation.

Here are my measurements I took for my wheels. They give you the details on how much back and front spacing I have. Hub and caliper specs are unique to my axles and Baer brakes.

"20x11 fronts with a 6.75" BS, 20x12 rears with a 7.75" BS"

Just for clarity,is this the Backspace you chose on post #40?
Looking to run the same wheel and tire size you have but I have a 70 c10 swb.
Axle is out of a 70 c10 longbed with leafs that I'm welding on the mounts for the truck arms.
Any help would be appreciated.

You really need to validate the measurements on your specific vehicle. Every different part installed can change vs. a similar (but different) combo. You can use the numbers he listed to have an idea of a possible range but need to measure your truck to know the hard numbers.

I second this advice.

The wheel sizes I ended up with are in that post, yes. 20x11 fronts with a 6.75" BS, 20x12 rears with a 7.75" BS.

But I'd 100% measure it myself, especially when ordering custom wheels you can't return.

Also note that the fronts WILL interfere with the shock mount. And they will likely interfere with aftermarket lower control arms sway bar mount unless you relocate it like I did.

If you're not wanting to mess with that I'd go at least an inch narrower in the fronts, but again, measure it!

Also keep in mind that your rear end might be narrower depending on if it's an early or late 70', which will affect the offset you need.

I wanted wide tires on all 4 corners for two reasons. One, to increase braking performance by having a wider front pad. And two because a square stance is supposed to help counter understeer, which we have loads of in these.

Hope that helps.

Thanks for the info,yes as stated in know I should measure my truck,just wanted base line numbers to start with,I did this with my 72 chevelle and the norm for 70-72 with certain components a 315 sq,front 10.0 or 10.5 wide 5.5 bs, rears 10.00,11.00 wide,6.00 bs 315 30 18 clears fine I've seen as a trend most of the times the numbers are close,the we double check to make sure it fits.
Thanks for sharing!��
Btw what is your rear,axle flange to flange? Thanks!

[siggyfreud]

This will look more in place long-term, but thought I'd pick them up now. Once the black bumper is black, and the truck is either a sand or Nardo grey color, I think these will look perfect. But for now they'll take up the exhuast hole space, and let me run the exhaust out back again instead of dumping under the truck which is LOUD.

[siggyfreud]

Been awhile since I updated this thread. I've been busy with my job, and slowly starting me future job/company.

On the truck I started replacing the front suspension. Out with the drop springs, in with some Ridetech Coilovers!










When trying to get the spindles back in I discovered Ridetech sent me balljoints for a 63-70 C10, and not a 71-72. They're sending me the right balljoints now, but will have change them out.

I also bought a Redhead box, and new steering shafts/couplers. A previous owner put in an Ididit column, but installed the steering shaft specifically how Ididit says NOT to, so that's neat. Going with a collapsible shaft to increase safety as well.

On another note, I started playing more with my 3d printer. I made some hose separators for the El Camino, which I finished for a buddy. Have a video coming soon about it.

Got some Dapper headlights in, which the owner loves. Not everyone's flavor, but I love them too and they increase nighttime visibilty greatly, while being DOT approved/safe.







Hose separator I designed and printed





And finally I have been working on a bracket setup for my Fuellab fuel filter. Originally I wanted something to bolt to the carb, but couldn't get the design how I wanted. So I switched gears and designed it to be integrated into a carb spacer. Here is the original drawing, then what I ended with after iterating a bit. The piece is printed in cheap PLA, about $10 worth of material. It took about 21 hours to print.

The final piece will be refined again, then cut from aluminum and anodized.





That's all for now!

I feel like I'm on the cheapest ship in Star Trek, with the slowest replicator they could afford haha.

But still, being able to take a design and a day later have a part is pretty awesome. Even if it's slow.

Cool build man. Im in for the ride!
