‘91 FSB Custom 4x4. 5.8L 351w. 4-speed auto w/ OD. Electronic TC. Mostly stock

I’m looking to put in a split bench seat in the front as well as replacing the rear bench with one that has shoulder belts into my 1991 FSB. Does anybody know the options available that fit? I assume most front row bench seats from F series extended cab trucks would fit, but unsure the year range. Any ideas???
I’ve also seen the write up about using a Chevy/GMC 3rd row seat to use for my rear. Does anybody know the year range and/or models of these GM seats that work with minimal modifications?
Thanks for any info!

Got to the Noobie forum and click on Baba Looie's favorite links. It'll tell you everything you need to know about swapping in a seat. It should also link to some rear benches with the shoulder belts. You'll need them built into the seats though because there is no mounting point on the fiberglass shell for 1989.

In general any seat from a Ford truck between 80-96 will fit the bracket. If you look underneath your truck you can see the seating brackets and holes. I swapped in a bench seat with a 50/50 split from a 1987 Ford Lariat into my 1989 Bronco. Plenty of benches in the JY, but not that many with a split just depends on how much you access the rear seat. I find that F250 and 350 seat generally have them due to the larger cabs

Yo Chinlund6,
Front, Installation info; "...On my 90' bronco I put in a bench seat and found that the body nuts for bench seat were on the floor pan already all that need done is drill thru. I used the stock seat for a 93 ford extended cab truck because it has a split back allowing easy egress to and from the truck..."

"the 40/20/40 seats from an f150/f250/f350 will bolt right in. just be sure to grab the seat belts as the center jump seat belts are integrated into the driver/passenger belts" by kemicalburns (Travis L) at

In same tread, donnor replied, "F-Series seats should fit in your Bronco. Do bear in mind, though, that there were different bolt patterns for the various seat types. Usually, the floor pan has captive nuts already in place for either of the two patterns. Remove the rubber plugs from the previously unused nuts. And, I would suggest you be prepared to chase the threads with a tap in order to clean them of any rust that may have developed"
In same thread, by kemicalburns (Travis L) added, F-Series 40/20/40; "...the bolt patterns are the same for all F series/broncos up to 96. u can run the 40/20/40, the bench seat or the regular captains chairs in the bronco..."
