Seat rail not lining up??

[enkei2k]

Hey guys/gals. So I just got a set of S15 seats and the rails are OEM Nissan S chassis rails it appears, so that they should all be interchangeable right? But for some reason, 1 driver side hole doesn't line up and 1 passenger side hole doesn't line up. All the other 3 are fine and bolted on. It's the upper hole closest to the center console (top right for driver and top left for passenger).

Now for the passenger side, the hole is actually raised so that there's no way for me to bolt it on. I know that these rails can't be skyline rails because i thought skyline rails are shorter by a few mm but in the rear, not the front. I can't move the driver side over any more because there's no room to move it.

My first set of OEM seats that came with the car was fine. Then I replaced those with Sparco rails and have the same issue I have now. I figured Sparco was aftermarket so the holes wouldn't be 100 percent lined up so I thought nothing of it. But now I'm back to OEM rails and they're not even close!

Any ideas as to why this is happening? Advice to get the last bolt in so my seat won't move around?

your rails could be bent ? make sure you don't tighten them down all the way first just put on loosely then try to line them all up..i had the same problem on my s14 seats..just be patient and don't strip the bolt holes like i did lol
