trans axle

Hello all, I'm looking to convert my 65' Corvair, but I'm having a hard time choosing between an AC or DC system. Does anyone have any "lessons learned" or "wish you would haves" using either of these systems?

I liberated the two beauties from a 2014 Chevy Volt transaxle, Gen 1. I was planning on linking the motors with a custom-made housing and getting rid of the brakes/clutches and other unneeded complexity. FYI: I have the Chevy Volt inverter, the original transaxle housing, accessories/parts...
