4 speed hump/swap question

Well I'll tell you my experience with this:
When I bought my 67 Barracuda some previous owner moved the 3 speed manual from the column to the floor without putting in a floor hump. They found out that the shifter mechanism would not clear the transmission and torsion bar cross members, so they notched the cross members so it would clear. Now I'm sourcing parts to fix it when I put my 4 speed in.
