They sit really nice. I was actually surprised at how well they fit. They put you up high enough but not too high that a tall person would be up in the headliner.
Install was not a problem. Once I decided to go ahead a drill the floor pan and not try to buy or fab up brackets to weld in, the install went really easy. The outside slider (next to door) sits directly on the raised section of the floor pan where the bench mounted to. Not the same hole as the bench but real close. The inside slider needs to be raised approx one inch to one and a quarter inch to level the seat. You may need more or less depending on your application. I used 5/16 bolts/nylocks for mounting, as well as, 5/16 washers to shim up the inside sliders. If you can, you'll want to put the seat in the middle of the sliders. Then position the seat so that the rear slider bolts are right above the rear floor pan support. If you're a tall person you may want to move the seat mounting position back more. This spot, I felt, allows the seat to adjust forward for shorter people or back for taller. The outside front slider hole will mount on the outside pan support. The front inside slider hole will need a 5/16 "fender" washer on the bottom side as this hole goes through just the thin portion of the pan. It will give you more "clamping" area to tighten up the bolt. After everything is tightened up I carefully rolled back my carpet and again, carefully cut to allow the carpet to lay under the seat next to the sliders. The carpet will lay low enough to clear the sliders up and back movement as well as high enough on the floor to cover the shims for the inside sliders. Keep in mind when positioning the seat that they are straight forward and the same distance from the tunnel. I installed my shifter after the seats were mounted but before rolling the carpet back.
I dumped my PM box, if you have any ??'s or whatever just ask.
