I'm putting the frame back together and just noticed that new body mount brackets (front two) won't line up with the holes in the frame - I do have one original front body mount bracket and in comparison to the new ones neither holes to mount to frame or hole for body mount bolt line up - go figure - should I just replace those and enlarge the holes for new bolts to go through and then worry about the body later? How did you guys do that, especially the ones that replaced body mount brackets on their frames during reconstruction?
