Changing 65 B-Body from auto to 4-speed. This is a console car. Have cut the floor for the new floor hump, but under the floor is a structural piece that follows the same line as the floor hump. This structural beam crosses under where the new 4-speed hump will go. Does this beam also need to be removed so the 4-speed tranny and shifter will fit? The structural piece I'm talking about is directly above where the transmission crossmember bolts (so it forms a oval and the transmission would sit in between the two pieces. The question - does the part of this "beam" that was directly under the floor have to be removed?
