Years ago, I bought a short seat at a local parts place thinking it was a third seat before I realized the brackets on the seat were for a second seat. I didn't realize at the time how hard third seat brackets would be to locate. I guess I could have fabricated something up but instead I bought an inexpensive folding third seat out of a '77. I pulled the seat apart, welded round corners on the seat frame and installed my '72 foam and fabric. Now I have a folding rear seat.

Full disclosure, I haven't got around to making or installing a bar for the seat clasp to engage onto.
