Forgot to say - the bushings are already on the arm...so I might just try my hand at making the hole bigger with a file. It seems to be the end caps that are causing the issue, I actually popped one off when I hammered the bolt back out. If that fails, I might just have to shell out for moog ones from rockauto, as the measurements there say the inner diameter is 0.51 inch. I bought the FVP BB6283 but didn't see the info for it, where it said the inner diameter was 12.2mm, whereas the Moog and Mevotech ones were 0.51 inch. Not really something I was expecting, since it was lumped in with the 67 Fury...no idea why there is a slightly smaller diameter.
