Took on a 87 mile drive and took this picture, no problems other then the break lights work intermittently but running lights always work. I think I’ll put a new headlight switch in and see if that fixes it.

Dig that truck! I'd love one in 2WD.

Re: 1968 GMC k2500 Stepper
 

Awesome. Those old tires hanging in there?

Re: 1968 GMC k2500 Stepper
 

They are doing pretty good actually, pretty loud and can give some vibration but I think ill leave them for a while.

Re: 1968 GMC k2500 Stepper
 

Got the bumper on, LMC had “bumper bolts” they are just carriage bolts not supper happy about it as it had the writing on the head

Re: 1968 GMC k2500 Stepper
 

Got some new reverse light housings, wirring on old ones was shot. Also can see the Dana 60 peaking through in the picture I was very happy to see it had the Dana. Changing all drivetrain fluids this weekend.

Re: 1968 GMC k2500 Stepper
 

Those rims look great on there.

Re: 1968 GMC k2500 Stepper
 

It’s a shame they would be well over 1500 for new tires and everything for them, I plan to just get some 17” steel rims and it should look almost exact.

Re: 1968 GMC k2500 Stepper
 

Here’s what I’m working with for floors, super good minus 2 pinholes in the driver side. Anyone know what would be causing water to come in from the bottom corners (kick pannel area)? Like where the floor and cowl vent meet?

Re: 1968 GMC k2500 Stepper
 

Drivers floor

Re: 1968 GMC k2500 Stepper
 

That is THE spot where there is ALWAYS rust, at least in drier parts of California. I think leaves get down in there from the cowl and soak in rainwater and stagnate in there.

That looks damn good to me, I wouldn’t mess with that!

Re: 1968 GMC k2500 Stepper
 

Any leak from the windshield will end up in that spot. Really, any moisture from above will collect there.
These trucks pretty much all have something in that spot if they weren’t always garaged.
That said, you have a great truck there. Enjoy it!

Re: 1968 GMC k2500 Stepper
 

Changed the front diff oil and tranny, front diff was very nasty and the tranny was pretty clean. And looks like the front diff didn't seal with the new gasket and has a smaller leak.

Re: 1968 GMC k2500 Stepper
 

Like 68bowtie mentioned debris gets stuck in the cowl vents and water then collects instead of draining. See links for more information on cleaning the debris out.

Water from wet boots and any leaks from the windshield area will also end up there too.

She's looking good with her new bumper. I do likes me a K model with white bumpers.

Re: 1968 GMC k2500 Stepper
 

I am saying this partly in jest: Quit looking, you can't handle the truth.

Note the similarities to your floor picture and mine (a little worse).

The first picture is my original floor (current build) which looked .... ok. Started digging (as usual). Second picture is the lower driver's side kick panel removed and the a pillar full of gooooo. Things only get worse.

Your truck looks really cool the way it is. IMO, if you just want a great looking driver don't dig too far. She will break your heart : )

Re: 1968 GMC k2500 Stepper
 

If…

It…

Ain’t…

Broke…………..

Re: 1968 GMC k2500 Stepper
 

Well I might have to fix it, there’s a pin hole in the kickpannel that’s letting water in and rusting the floor worse.

Re: 1968 GMC k2500 Stepper
 

Ill have some more coming to the thread soon I found a step side bumper and a new box with the same color and patina in great shape and should match perfect.

Re: 1968 GMC k2500 Stepper
 

Any Updates????? Pics!

Re: 1968 GMC k2500 Stepper
 

That is one cool truck!

Re: 1968 GMC k2500 Stepper
 

Got an update for you guys, truck is parked for the winter, but before that I got a super nice matching box! Big upgrade.
Not bolted on yet, but next on the list I think will be a NP205 swap and then gears to possibly a 3.73. I don’t want to mess with swapping a overdrive in and just need to be able to go 65 and 3.73 seems to be perfect is there a chance that gearing would be not enough for the truck or would it be fine?

Re: 1968 GMC k2500 Stepper
 

Three Seven Three is perfect for these trucks. That's what I have in my '68 C/10 Stepside, my '71 GMC Jimmy, and had in my '67 K/10 Suburban.
Nice looking bed.

Re: 1968 GMC k2500 Stepper
 

Yeah the 4.56s are pretty crazy it goes about 55-60

Re: 1968 GMC k2500 Stepper
 

Going to be working on it here in a week or so when it gets nice out,on the last drive the vent window swivel pin broke so I’ll need a whole new vent window it looks like and I’ll rebuild them both while there. Anyone have any experience with interior red parts matching correctly? Worried the LMC red interior parts look off.I need a dash pad and arm rests.

Re: 1968 GMC k2500 Stepper
 

Wow. The D/S Vent Window swivel function went limp on my '71 GMC Jimmy this summner. I was relying on it for forced air breezes, ala System Two Forty.
[Roll down 2 windows and drive at least 40 MPH].
I hope the pivot shaft ain't broke.
For the rest of the summer, I tied it back with a bunji cord. Works OK, but it's a PIA to remove if you have to secure the truck.
I have a pair of '72 Doors I can try to cannibalize.
