I was concerned about the transaxle strength.
I had the transaxle and a motor adapter already for it, so just put it in.
In fact, I picked up two C5 corvette differentials I was going to use,
no strength issue there, just more fab work and expense.

A ragtop is not really ideal for this kind of car.
Might just go old school with a chopped top awd electric ghia and build it from scratch.
