Anyone know of a 231 for a 4cyl TJ kickin around? I need one desperately. Also need the front DS too!

FWIW, what are you trying to do with it? The different trannies have different outputs, so the splines might not match.
Otherwise all the 231Js are basically the same... Some have a different setup for the vacuum harness for some fuct reason.

well, trying to replace the one in my friend's TJ that literally exploded on the highway. I tried using a 21 spline from an 89 YJ 4cyl, but it's different. It has 4 mounting bolts, instead of 6, uses a mechanical speedo cable, instead of an electric one for the TJ.
Also the tailshaft is way different. I don't think it's gonna work at all.
