I decided to replace the upper control arm bushings on my 64 post. I cannot locate a source for these, the norm-NAPA, Rock Island, etc does not carry one of the two needed anymore. I don't know which one of the two they they carry. I am assuming probably the one for the ear on the differential is different and no longer available. Thanks

 

The rep at National Parts Depot says the 64 upper bushings are the same size, the difference is that 64 only used one on each end. So I ordered a pair for each side. 64 Chevelle and F-85 control arms are the same. ( I hope)
