Those old style flat seats from the 60's and 70's may look "classic", but they are really hard on my back and not that great for cornering. I need seats with aggressive side bolstering for lower back support.
We lost a number of good threads on seating in the crash.
The problem with putting in seats out of a salvage yard or another car is they don't match the rears or the original interior. This leads to a need to recover the front and rear to match. Up here in the frozen north, custom auto upholstery is very expensive.
My 300ZX cloth seats check off all the boxes. However, they do not match and have a slight smell of body odor that I have not been able to get out.
Both Procar/Scat and TMI offer rear seat covers for 2nd gens that match their fronts. Most of their seats also tilt. TMI has a lot of styles and choices of seat materials and colors but they are more expensive. Here are the links for both:
