Thanks to a kind Forum member, I was able to replace the frames on my 77 front seats. If you can use my old ones, I will give them to you if you pay the freight (UPS or US mail). Both bottoms need the springs replaced. I have extra replacement springs you can have for $10.00 for the pair. The passenger side is pitted but could be blasted and used. The drivers side is, well, it exists but is badly rusted. I can send pictures. Slides are not included.
