I have a set of 88-89 crx si seats. Will both years bolt up into a 90-91 si? Was hearing 88 was different floor pans

 

Try it.

 

would love too. Seats are at my house my car is not..... Thanks for the encouragement tho

 

Wonder why we aren't checking part numbers?

Or if you did a quick 10 second search you would have found the answer is "no".

 

As stated above, it will not work. You can take the seat pans off of your 90-91 seats ( assuming you have them) and swap them out with 88-89 seat pans. There should be a DIY on this on here and it should only take about an hour at most.

 

Tried it before they dont fit ended up custom fitting them with civic Rails
