I moved the right bracket back almost a half inch to align the holes and then the core support holes are off. Just wondered whaat your expericene was. thx

Hey JWALT,
The holes that lined up for me were the center hole of the DIY bracket and one of the top rivet holes for the cross member brace on the inside of the frame. Even though the holes "kinda" lined up, I did have to wallow them out a little.

Whats a little strange though is that on this last go round on my truck (the engine swap), I pulled the front sheetmetal off. My core support was rotten at the frame / mounting area so I picked up a new - used one off of a later Burb (thanks Randy!). When I went to install the core support, it seemed as though the mounts were farther apart than on the original. I really had to wedge the long support bolts in and then crank down the nuts.

I just chalked it up to tolerances being a little loose on the old truck.

One other thing that it could be. I do know that mine was in a wreck on the passenger side at one time. I don't think that the frame is affected but Im pretty sure that the firewall on that side is pushed in a little. Since the inner fender is supported by the firewall and more or less sets the distance for cab to core support, there could be a discrepancy there? You might want to take a few measurements (core support to cab on both sides)?
