Default 88 yj 4.2L (rebuilt with stuff), yj np231, rear d/s

the engine is out of my 88 yj has around 10k miles on it. Has be rebuilt , bored .040 over with new pistons, cam, motocraft carb, HEI ignition upgrade. Ran very strong....could spin the 33s in first gear with 3.07 gearing with no problems. Lookin for $400 *sold*

NP231 is out of the same 88 yj. Never had a problem with it. Tore it apart last year thinking the chain was stretched but it looks brand new. Has no SYE just stock. The rear seal needs to be replaced as that leaks but easy fix.

than i have the manual 5spd beougot trans.....its

also the rear driveshaft
