Diff Dilemna! Need opinions!

I understand everyone is trying to help, but i want the car on the ground to test and then move from there..i dont think one launch will kill it, and if it does, well then you can all i say i told you so lol

but like i said, one bit of hop and im jumping on the suggestions and putting them into action

Believe me, I'm on your side. Just check that axle to be sure the flange is true. I don't want to see your trans end up like mine did. You cant tell by just looking at that picture but the tail shaft stayed bent about 1/8". Like Crackedback said "All it takes is once".

By the way, many years ago, I broke an automatic trans when a ring gear let go and know of 2 others who took out transmissions because of problems that started in the driveline. I will look forward to the results of your test...
