Damn...I wish I'd known a few months ago...I had a decent condition 83 J10 that needed some love...I was halfway through a tranny swap (Auto to 5 speed) when some other problems came up...couldn't find a buyer so I had to send it to a junkyard. If you're still interested and in the Madison, WI area, I might be able to find out where it's sitting(and if it's still in one piece) lol Oh and it had the 360.
