Re: 86 Suburban daily driver

I hope you checked the manifolds good because they prone to cracks. They look like they been running a little hot the on the right mostly. The cracks mostly happen at the v off the ports. Just in case you did not know good luck.
looking pretty good so far for the burb.

Thanks for the tip, I did not know that so I'll have to check them out good.

I gave the manifolds a quick dusting in the blast cabinet so I could check for cracks, these are good to go! Were rusty, but other than that just fine.

Re: 86 Suburban daily driver

While planning for my notch, I had a chance to stop at a Pick-N-Pull and grab some more parts off the list. Realizing how much I use the rack on top of my DD suburban, I wanted the utility of one for this one too. I grabbed the rack off a 2005 Suburban, the cross-bars will need to be narrowed just a bit and it'll fit great! The way they are put together, it will be easy to narrow them. I also want to not get rear-ended in traffic if I can help it. The LED taillights I already added plus this LED 3rd brake light off a 2004 Tahoe should help with that. Nothing is mounted yet, just sitting there for a preview.

Re: 86 Suburban daily driver

I've been planning for my notch for a while now. I've now come up with a solid plan and I've started in on it. It may take me a while because lots of other stuff going on, but have a start on it.

First up was fixing where the wheels sit in the wheel wells. It drove me nuts that they weren't centered. I also couldn't live with the u-shaped flip brackets. I know there are thousands of them out there....but doesn't do the job for me. My number ended up being 1/2" back from the centering pin.

Re: 86 Suburban daily driver

Got my template figured out and transferred it to 3/16" plate. The outside will be plated, the inside will be boxed, and the notch cut out and welded in. They raise up about 1" above the original frame rails, and will be capped. All of this will be below the floor. The inside of the C-Channel frame also needs to be trimmed, because it is in no way straight enough for boxing plates! I had to remove the body mount and will trim 3/16" out of it before it goes back on.

More to come!

Re: 86 Suburban daily driver

Got a decent start on the notch this weekend. There was quite a bit more fine tuning I had to do with the plates I had previously cut out, but I'm pretty happy with how it's turning out. I started out with cutting out for the notch, then welding in a piece of 1/4" plate I bent in the shape I wanted.

Re: 86 Suburban daily driver

After I had the basic notch in, I worked on boxing the inside of the frame rail. Not fun working out of position with obstacles in the way, but I did make it happen.
