I can get upper control arm shaft but how can you make it work with the screw on bushings the 64 has? I'm thinking they really sell a Chevelle shaft and it has the press in bushings. Whats the trick?
I'm gonna say you would have to use the whole 66-up A-arm to use those offset shafts. The stock-type 64-65 shafts are fairly scarce. The only manufacturer I know of is Rare Parts.... and sold by Autozone, NAPA, etc. Are you sure you need offset shafts?
New ball joints and still off 1+ degree's. I could get 64 Chevelle A-arms, any chance they interchange?
