Is there a source for the 1975 H/O swivel bucket seat upholstery ? I'm assuming the seat and back have more of a deeper contour so the reversible cushions fit. I can probably have the cushions replaced but am concerned that the only upholstery kits for the seats are for the standard swivel bucket seats without the reversible cushions.? I thought Olds (and maybe Buick or Chev. had vehicles with the same seats in that time frame? Since my old seats are pretty yellowed and the seams are splitting out I wanted to get those seat belt guides installed but there seems to be something missing in that area to "screw into" for that seat belt guide escutcheon? There didn't seem to be anything solid under the upholstery other than going further toward the back of the seat to hit the frame! Anyway, this is my next project. Thanks.

 

From what I understand, swivel seats with reversible seat cushions were specific to 1975 Cutlass only.
