Tough to read that you used a 71

BTW you will probably need to rebuild your half shafts and center diff if you haven't already I exploded several of them back in my day I have a nice set of Eaton unit with 3.90 gear that has lasted in the back of my 75 after slowing my car down some. I was stubborn wanting to keep the stock rear setup using a 420lbs. composite rear spring (stock is around 200) Then again you being electric who knows. I understand instant torque and all which should mean that when I was running a measly 435lbs. at the tire I cracked those gears like I was dropping an iphone in a blender. I stepped up and ran over 835lbs. of torque on alcohol and popped 1 Auburn unit and slowed down since and still running the eaton with around 550 torque at the wheels now.

Half shafts, yeah those will break first, gone through 6+ over the years usually driver side.

Now for Safety:
Use a lakewood bellhouse if you want to keep your legs and reinforce the drivers seat. trans blanket also advisable. The aluminium stocker is a joke like trying to deflect a bullet with a piece of paper add in the fiberglass floor. I know this will be a show car but many people lost toes or legs when that trans clutch goes kaboom. Yup blew that up also except I had the Super T-10 in mine swapped over to a M-22 rock crusher and exploded that until I did the smart thing and built a th400 up to handle the power.

don't want to sound like a Jerk but the reason I parked my Vette 5 years ago is because I wanted to see my little girl grow up almost lost leg after trans explosion had fuel tank ruptured when a half shaft blew and grafted in metal to the drivers floor to remount my seat so next time the piddly seat bolts don't snap when the parachute opens. Parts break especially on a 40 year old car. Be safe
