Putting new upper control arm bushings in a 69 super bee a12. The leading bushing was what I expect the rear bushing has what appears to be another thick collar pressed over the installed bushing. Never saw this on the 67 and 67 b bodies I’ve done in the past. It doesn’t want to come off the bushing, is it sacrificial? Do I have to cut it off to get the bushing out of the arm ?
