So, after no comment from the Binder Bulletin gang, I decided it would be best to put in the new bushings all around before I weld in the rockers. Today I went at it and figured, heck, since I have the body lifted, I might as well also put in the lift, too. I started on the driver's side (the body repair is on the passenger side). Got the two middle mounts in. Well , almost.
The front body mount (under the driver's feet) doesn't line up. The bolt runs down at least 1/4" too far outboard. Hmmm. If anything, if the body was going to shift, I would have expected it to move downhill, towards the passenger side. I'm not going to sweat it too much just yet, until I get all the others in. I don't think that the angle at which the body is sitting would make that much of a difference, but we'll see when I jack up the other side.
The driver's side mount has been replaced at one time and could have been drilled a little too far out, but there was a good bushing in there when I took it apart, so... we'll see.
Also, in the lift kit, there are two bolts longer than the others (and wider). The mount forward of the rear wheel needs a bolt longer than the others, but this longer bolt is too fat to fit the sleeved hole in the body. I'll see how the rest of them go. Might have to get a new bolt. Don't know how I could drill it out to fit the large bolt, can't get a drill in there.
