Re: The Definitive 67-72 Seat Swap Guide Thread ....
1988-94 (in this case a 90) Bench. Outer front factory holes line up with the 90's bracket. Drill new hole for rear and add a 7/8" spacer (I used a 1" to 3/4" pipe adapter) and reinforce the floor. I also used the 90's seat belts and if the tank is out all the factory seat belt holes work with the new belts.
