Parts or complete new unit............. Have not heard about this, Mike, would that be parts to upgrade my old tranny or will I have to buy a whole new unit............
While not a 5-speed, I have heard of a 4-speed Muncie with over drive (3rd is 1:1) - http://www.m-22.com/m21od.htm
The Muncie 5-speed project is not looking too good right now: http://www.chevelles.com/forums/showthread.php?t=92851 Sounds like George at AutoGear has stalled out on this effort.
