52 Chevy Tranny swap

[wildfifty2]

I am converting the 52 1/2 ton over to a 700R4 transmission and Chevy 12 bolt rear end out of a 68 Camaro. The transmission will be mounted up to the 235 CI with an adapter. I am assuming that I will need to cut out the cross member that supports the bell housing mounts for the original four speed. Just curious if most people cut this cross member off removing the center section or attack the rivets that hold it to the frame and remove the whole piece? Thanks
