Need new flex joints for my rear rustys adj arms. I want to know the thread pattern to see if I can buy currie jj's instead.

Either 1-14 or 1.25-12. You can swap in a 2.5" JJ with either of those shanks. Just measure the Rustys shank and order the appropriate JJ.

Good call on the swap. You're swapping out fool's gold for gold.

I think the uppers are 2" and the lowers are 2.5"

Correct. The uppers should either use a 3/4" or 1" shank. Just measure and order.......
