Regarding this topic I'm prob going to get the typical "this has been covered a million times topic" but in any case I've done my research and I've actually done this swap but it hasn't really worked out the way I've wanted it too. I had a 91 crx HF and I bought a set of LS DC integra seats and installed them but using the bottom of the HF seat pans an swapped them over to the teggy backrest and butt cushion. Now doing this I was able to use the HF rails since the pan was from the HF seats BUT the seats after they were done were so far back adjusted that it was actually uncomfortable to drive. I wasn't able to sit them correctly after I switched the pan. Now I have a 91 civic hatch std and I would like to put in these del sol seats I have. I have a pair of ef si seats that are way too torn up to use but the rails are good any suggestions?

 

You can either put the si rails on them or modify the del sol rails for fitment.

 

do the rails bolt right up?

 

From one to the other? I believe so. But the other seats will need your rails to fit I think.
