TKO 600 ....Anyone done one?

Thanks for the input guys. Todd, I had decided on a TKO 600 because I will be drag racing the car and I wanted the extra strength over the TKO 500. I don't have the car on a hoist right now to check this but if one of you knows whether or not a person could completely remove the factory crossmember, fab a complete one like Scott did then later replace the original one with out pemanent damage to the car. This car was originally an automatic so somewhere down the road I would be replacing the forward part of the tunnel anyway. If this mod could be successfully done I would probably opt for a Gen III Viper 6 spd like I originally wanted to. The reason i dropped the Idea for the Viper trans is because Keisler said it requires a lot of mod to the crossmember. Kev
