    What does the car have for a cage? Frame connectors? sounds like it has to much flex. Just putting in a powerglide won't help breaking the housing IMO

    How is the rear end in the car? leaf springs? ladder bars? 4 link?

    Changing to a powerglide will not fix the cracking problem.

    The powerglide will of course have a higher 1st gear, taking a little off the intial hit. But sounds like you should first look into maybe a motor plate, mid plate, engine travel limiters and roll cage. But do stay with the urethane transmission mount. IMO

    yes, i agree, if you want to go solid on the tranny, you are going to need to put a motor plate and tranny plate on the car. If you just put the stock replacement solid mounts, the result is a broken bell housing in most cases. Cars are weak and do alot of twisting and the weak link is something solid. Check and make sure that when the engine mounts are installed, that the tranny mount lines up with no bolt or nut in the crossmember. If its crooked, theres the problem!

    Regardless of what is done to the car I would stay with the urethane transmission mount. IMO

    transmission

    I agree, stay away from the solid trans mount. Sounds like the body is flexing. Recommend the cage and front and rear plates.
