I've heard you have to keep the upper bushing steel shells, in place, as they're not available with replacement bushings?I know that the 64 is a one year size, did a search and found the GM part # at 50$ a piece I would like to find them a little cheaper. UMI has poly ones at about 40$ but really don't want poly. Anyone have a link to other brands?
Only the bushings are a one year deal..I may be confused, I know the bushings are a 1 year make for the 64, are you saying the upper arms are also a one year make? My overall plan is to have adjustable uppers and non adjustable lowers. With the LS swap I know that adjustment will be needed for pinion angle.
