Here's what I did, the seats are out of a 80's Camry they fit real nice and you can set them up with these brackets or just put them in. If you just put them in without the brackets they sit real low in the truck so you'll have lots of head room and adequate leg room. If you are under 6' then do the rear brackets to your height, the taller the bracket the more leg room will be created. The brackets were made from 2x1 square tube. I set my rear to the floor with no bracket and the front with the bracket and I'm 6'2". I had plenty of leg and headroom. The passenger side had the front and rear brackets, the rear was on the 1 inch side of the tube to boost my Co-Pilot's view.
