67-76 floor into a 65...

Makes perfect sense then! I wouldn't want to disassemble half the car to get it to come in from the bottom. :BangHead: That would be the only other way to do it in one piece. Your way would be much easier and just as effective for a sedan.

Not possible to go from under as the floor sit on top of the sills and crossmembers. It's an easy job on a hardtop or convertible. Much more complex on a sedan.
