Porsche sport seats?

[CRCGuy]

I am looking for late 986 or early 987 Box but I know with 100% certainty I need the sport seats (but not sport buckets). I have major back problems and have sat in both and the sport seats fit my body perfectly and felt great--standard seats I found uncomfortable after just 10mins.

Question:
1) are seats interchangeable between 986 and 987 (only care about driver seat really)

2) What would a new OEM seat cost? (expecting disgusting answer)


3) would it just be smarter to find aftermarket seats if I find one that is comfortable?

Any advice appreciated.
