Some people want to install the OE style 73-up rubber bushings to get a smother ride resulting from the thicker rubber bushing/metal shell housing style of bushing.
Others swap to the 73-up stuff for the ability to use Poly bushings for 'better' performance using that same metal shell housing style of bushing.
The original 72 bushings are rubber lined steel & designed to pivot via the internal threads. I like to think of the OE 63-72 design as a budget Delrin set-up (it pivots freely & is not all cushy).
So, to answer your question is to follow the ride quality you desire.

Thank you for the info! Don’t think I’ll be making any changes right now but it’s good to know what my options are.
