? Yes, I still need an answer. It hasn't been critical yet because I'm still working on the inner rockers and floors. (more on that in an update email I'll send).

The MPC for a 65 (coupe) body shows different supports for the seats than a 76 (convertible) body. It also shows the part I'm asking about for bucket seats, but doesn't show it in the 76 body schematics. I'm trying to find out if the bracket will fit in a convertible, or if it's even used, and if not, is there something else or just a hole in the floor. I've included snips showing the parts. The first is the 65 body with bracket in question. The second is a 76 body with floor support, but not the inner bracket. The second pic also shows part 617B70 as the outer rear seat support on the underside of the floor, but nothing for the inner rear seat (Bucket) support. I'm trying to find out what I need to convert to bucket seats, and mimic the factory.
