Bench Seat Interchange

There is a lot of variation in the back seats. Obviously, convertibles are different from fastbacks which are very different from 2-door HTs and sedans, and can't be swapped. The front benches differ a lot in shape (hi-back, low-back, headrests, split, center arm rest) but they probably all fit the same track -- the issue is whether you need access to the back seat or not.
