I don?t really want to put a bunch of time and or money into a 231 because i really want a Dana300 and any money spent on a 231 could have gone to getting a 300. The SYE i?ll be doing won?t cost me anything and it will probably only take an hour or less to do. The Later 231s have a long fixed yoke and the drive shaft slip yoke slides around it, it?s a really goofy setup.

Rubicon express makes a flange that splines on and you drill and tap a hole to bolt it to the fixed shaft that you cut down. So i figure I can machine a montero pinion flange to be a pressed fit, use a dial indicator to check for run out and weld the flange to the shaft.
