There are several strategies that have been used to fit a G50 in a t-bar car
- move the engine back
- use the short bellhousing version of the G50
- shorten the trans main shaft
- install a G50 t-bar tube
- various combos of all of the above
I used to have a pic of all 3 of the trans, 915,G50, G50/21 laying next to each other. But I can only find the G50/21, it's much longer than the others.
