Anyone running a th400 in their a body?

Maybe should try these guys. I'm involved in a 4L80E 6 speed auto build at the moment. Had to cut the whole tunnel out and the torquebox cross member.

The Reid stuff is real nice! I started with a Quick Time bell (4L80 to Big Block Mopar)and it leaked like crazy as it was .006" off from side to side and it bolts to the cast pump surface which obviously isn't flat and will never seal (I was warned prior). The fluid crept right up the bolt and leaked all over from where the bell meets the pump. I have since switched to a Reid bell for a power glide to BB Mopar with an adapter plate and modified/machined pump from CK Performance Racing Transmissions. Everything is machined perfectly flat and o-ringed, so bottom line....no leaks! It's a much nicer looking set-up too!
