CRX seats

Ok heres the deal, I am looking to replace the seats that are in the crx. What STOCK honda seats can fit into a crx and what rails are needed for them to fit?

EDIT- 1991 CRX Si

none. you will need to pan swap whatever seats you want onto a 90/91 pan

89 crx with door mounted belts should also work. there are no direct bolt ins but crx seats, you will have to pan swap.
