I'm not sure about the 89' seat but I think they are the same as the 92'-97', I installed a 95' bench seat in my 79' super cab, it was not a direct bolt in but there is not much fab work to make it fit, for the rear bolts on the seat frame I had to drill & tap a new hole on each side & install a spacer to bring the back up about an inch, then for good measure I put a nut on the bolt under the floor(where I drilled & tapped the new hole the material was only about 1/8" thick)
On the front is where most of the fab work is, the front seat mounts line up with where the "under seat" part of the floor breaks over and goes down to the floor boards where your feet sit, I used a piece of 3/8" x 2" flat strap and bent it to fit the floor, thendrilled & tapped the plates, next I bolted the seat in at the rear and bolted the plates to the front seat mounts, and tacked them to the floor, after that I removed the seat and finished welding them to the floor,
It sounds harder than it really is,
I have pictures of the seats in my 79' supercab gallery, but no pictures of the mounting,
