1965 A body 4 speed ball and trunion to Slip yoke ?

Those are nice and all, but why?
Cuz it’s nice and shiny?

In my case, I didn’t have a ball and trunion driveshaft to start with. Sounded like OP needed to modify, or needed a custom driveshaft anyway.

If I had one that worked with little-to-no modification, I most likely would have used it.
