73-75 vs 76-77 bucket seats

[dagnabbitt]

I saw your post on TCKR's thread and thought I would ask here - instead of there - about the differences between 73-75 and 76-77. If you would post some pics of what you got that would be great, there is insufficient info out there regarding squarebody buckets, IMO. What you have could be helpful.

I was lucky enough to score some "medallion" style buckets that I now know are 76-77 seats, but my goal is to reupholster them into 73-75 versions. I am wondering if there is any reason I could not simply refoam and recover them, or if there is some structural difference that means I should abandon this idea.
