We are also new to the forum and in the rebuild mode of our 62 holiday coupe and stuck at the upper and lower ball joints. No one in our area can even get a part number. Where were you able to get your upper and lower ball joints as parts people here are saying the 62 dynamic requires 62 joints period. was hoping there was a cross reference but so far no one here has found any. We are finishing brake rebuilds and front end is next but we're stuck at the ball joint replacements right now. Any info much appreciated.

I moved your post to its own thread instead of ressurecting one that's 16 years old.

Have you looked at Fusick for parts?

NOS GM or Moog, probably on eBay. Expensive. I can get you the GM and Moog numbers when I get home.

There are also places that will take your old ones and rebuild them, but I have never had that done.
