Removable floor hump.

Mine as held down with sheet metal screws and I put the self-adhesive window weather stripping around the bottom edge of the hump. I remove my two bucket seats which is real easy and my threshold in the carpet comes out. Then I can get the two top transmission bolts sitting in the driver seat... All goods takes about 10 or 15 minutes both ways... And yes I've switched back and forth to a 904... Just need a different slip yoke...
