Apacheman, here is a pic of a SM420 (4onthefloor) tranny used at that time matched up with a modern 2sp auxillary transmission AKA "overdrive unit". It is made by Gear Vendors. http://rides.webshots.com/photo/2234118210071636143MfdrhX I chose this route to get the best of both worlds. The granny gear, 4th over, and the 5 other gears inbetween.
