Oh gosh, yes! I was just making sure everything was trimmed narrow enough to fit.

I'm taking a break to eat. Spent multiple hours trying to get the cab square, then finally gave up doing comparative measurements left to right and just used a plumb bob:

I should have done this ages ago. SO much faster

Exploded the truck again (200" wheelbase anybody )


And started making my new cab mounts


At the front, my mount point is 6-1/4" outboard of the frame rail, and at the rear (using the inner hole of the original shackle mount) I'm 6-3/4" outboard. The material being used is 3"x5" box tubing, 3/16" wall. Should be heavy enough!

I'm going to perimeter weld the mounts on the outside and probably a few 1" beads inside, but I suspect I will put a pair of 3/8" bolts through the mount and the top flange of the frame rail, just as a safety.

I'm using 67-72 2wd cab mounts, which are 1-1/8" tall. In the front, that gets me exactly where I want to be just with the usual washers and such. In the back, I need a 2" thick spacer to meet the floor (the rear mount sits 3/4" higher to start with, and then it's an additional 1-1/4" up to the floor pan inside the channel of the mount). So I'm going to cut a piece of 2"x4" box tubing and box the ends to make the spacer. That way all four of my frame mounts are identical to make, easier for me.
