1975 Camaro rear spring insulators the wrong size???

Yeah, that bottom plate in that pic is a little distorted.

I ended up greasing up the pads with silicon grease and assembled the springs and then clamped the bottom plate on as tight as I could get it and got the bolts started and the nuts tightened until the clamps were loose. Then I cranked the clamps a little tighter, and then tightened the nuts, and went back and forth like that until I had an eighth of an inch or so of gap on all four corners and the pads were as well squished as they're likely to get (for now). I resisted the urge to fit one-eighth-inch spacers between the perch and bottom plate because I anticipated having to tighten the nuts a little at some future point.

Those nuts on that bottom plate look a little "off." They make me feel better about the wide-shouldered lock nuts I used on my sway bar brackets.

Maybe this might work after all.

I need to either look at more photos or stop looking at so many photos. I went ahead and added a pair of 7/16" washers between the perch and bottom plate at each bolt and pulled everything tight. That at least managed to silence that one voice in my head.

Normally I disregard the voices but this particular one always gives me such excellent advice.

were the shackle bushings rubber?

Yeah, I think they are. Smells like rubber, anyway.

I just got through replacing my springs on my 76. I ordered the Spring Pad set from Classic Industries direct from them p/n R654. I was able to get metal to metal contact on the lower to upper plates without any issues. I smeared silicone grease over the rubber pads before assembly.
I also got the T Bolts - P/n 481949 from CI.
The Ubolts came off the Rock Auto site for my model year. They were longer than the originals and I had to cut some off to get in between the brake line and the axle. The gap was very small.
