I have seen a few sites offering buddy club seat rails for 88-91 civic. but aren't the 88-89 and 90-91 rails different? they don't offer two diff ef rails only one. whats the deal with this? i contacted both dealers with no response.. so i figured id ask here. im in need of an 90-91 set

 

yes, 88-89 have narrower brackets due to narrow bolt pattern, the 90-91 is wider. You can get 3/4 bolts to fit I believe.

 

Im just trying to figure out why buddyclub is offering the rails to fit all 4 years? and not separating them i just don't want to buy it and have them only fit on an 88 or 89
