Here's what Marlin said would work. Call his shop for more details as far as shift forks or internal parts. His shop also told me to try Toy Connection for the shifters. I have a set on the way for my trans.

The V6 R150 ('88 and newer 3.0 and 3.4) bases will work just fine on a R151F. They feature an added vent for internal pressure. You just need to turn the base 180 degrees from the stock V6 location before installing it so the left and right trans handle pivot pins that are are riveted in the base, are directly in line with the shifter detents that are bolted on the left and right side of the trans, directly under the shifter base pad. Also needed is the metal oil Salinger (very important), and 4-8x1.25 mm bolts, 30mm long. However, you can use 4 of the 6 bolts on your W56 base as well. They are in fact the same bolt. You will also need the V6 shifter as well...
Backup light switch will bolt right in
