Well first off I have no intention in copying anybody. The ferambo is an awesome car, but not quite me cup of tea great way to display your work. I have a truck that does this.
The trans should be able to be paddle shifted since a 4L80 can be paddle shifted.
The distance from the rear axle center line has to be pretty long, so that will leave some cars out. I doubt it would fit a camaro, it might fit a 66-67 nova. If we did this to Johns nova he could have that back seat he always dreamed of.
I have been thinking of using it in a street rod, something with a short interior section and a 2 seater. I have a 36 ford 3 window and think it would be cool in that, but maybe to long. But what engine do you hook it up to?
Maybe this

I was also thinking an almost flat floored 4 seat bubble top impala.
Pantera or GTM super car would be cool also.
