Re: Rear Bumper Bolt Pattern Thread

My eyeballs say that hole is approx. 1.3/8" from the rear and 1.3/4" from the bottom. At least the vertical matches up. Interesting. So in other terms, if we used the same brackets my bumper would be 1/2" further back. This may be why the outer brackets differ between my application and others.

Looks like the horizontal position of that hole is the same as my C-20, 2WD leaf spring.


Keep em coming, I appreciate it a lot. At some point I'll dial this down. Had I known this would be an issue I'd have solved it before the frame was finished. Probably should have anyway. On a side, I know I'm not the only one with that rear bolt location. Here's another, post 6. Bet it's a SWB 2x4: http://67-72chevytrucks.com/vboard/s....php?p=6742315
