My dad cut his on his 1966 Vette when he put the SS700 in. He cut the crossmember at an angle just outside of each exhaust tube. Added flanges and uses 3 bolts on each side to secure it. I will say it made installing the SS700 much easier but I still have mixed feelings doing that to an original car. Also I don't know if the C2's have more or less room than the C3's in the area where the cuts were made, so this might not be the easiest way to cut the crossmember on a C3 with the body on.

I've done it on my 69 vert. I put in a 5 speed. With the recommendation from other members, I pulled the plug. Bull shark had some pics that I copied from. But he had access to a cutting machine and made a nice flange that was welded to the crossmember. I did mine a little different. His has the matching hole in the crossmember, mine I made as a whole plate. If you do cut the crossmember, make sure you measure the distance of the trains mount from the drivers side to the mount bracket and then from the passenger side to the trans mount. It different on both side. That way when you go to have it welded, it would be it the right place. The trans mount is not centered on the crossmember as I found out later.
