I just got a 90 crx. The seats are only in with 3 bolts and the rear inside of both seats are floating but all the others bolt in fine. what rails will work so I have all 4 bolts?

 

Start off with figuring out what kind of seats are there, whether it is a honda, other brand, or aftermarket. Than you will have a good staring point on what conversions are needed to get it to work. You know, one picture is worth a thousand words... Take a snapshot and post it here for people to identify things if you cannot do it yourself. Keep us posted.
