Thanks for your input ,guys. I just came in from the garage P S T was closed .I'll ask someone else there tomorrow,as I already asked that question and the first guy says no problem. Mike and I went to Sinclair Impala for parts yesterday .{ A 388 mile round trip to the parts store} He tells me his friend just put a set in a 55 and had a squeaking problem.TECH, these are the polygraphite bushings that P S T sells.Oh Well, the first set proberly lasted 40 years. If I go original and they last 40 more ,I'll be almost .101.Doubt that I'll give a rip by then , YOU THINK?
