I'm putting a passenger buckets seat in right now and I swapped over my crx rails, but the alignment is off a bit.

I'm just wondering it it would be ok to just drill and put a bolt through or should i weld the rails? The two on the left bolt up but not the right. Pics should help.

 

Seat mounting points are different. 88 and 89 share one and 90 and 91 share one.

 

That seat isn't from a hatchback. Which base and rails were used in the hatchback?
