Any 57-58 Buick experts on this site?

Does anyone know if the 57 and 58 BUICK front spindles are
interchangable?     Thanks trying to do some suspension upgrades.

I think '57 stands alone and was the last king pin front end. I believe '58 had ball joints. There was some discussion recently on this same issue over on the HAMB. You might do a search over there.

I looked in the Hollander, the spindles are different numbers from 57 to 58. The ball joints are the same though. My guess is you could interchange complete spindle assemblies, but not just parts.
