Yes, your comments are correct. I had bought an aftermarket set of upper control arms that come without the cross shafts. The kits was advertised for all A-bodies in the years mentioned. As was said, at least the Skylarks are different. I ended up buying a replacement set of cross shafts for a Chevelle in the same year and it all bolted together fine. So.... All A-bodies are not created equal! The suppliers should not treat them as if they are.

Now, if you just want to replace the bushings in your stock arms to run poly or Delrin bushings you will have to get some Chevelle a-arms. I am not sure if you can run aftermarket crossshafts with the screw in bushings. Since the Buick arms are threaded you can only replace the bushings with new stock style screw in bushings.
Hope this helps. There are not a lot of 64-65 Buick cars on Lat-G or Pro-touring so information can be hard to find.
