Older Mustang bucket seats bolt in and bronco seats as well... Look on www.fordification.com and they have heaps of info there for 70's F100s. Great site for info on your truck. I used 2000 and something (forgot the year) Jeep Liberty tan leathered, powered and heated buckets in my 66 F100 but had to do some fab work on the mounts since one side was much taller than the other and they were much too high. I dropped them down as far as I could and they are very comfy and look great. The head rests come off so that is what I did as not to block the back window. The top of the seat is not flush with the bottom of the rear window which I didn't like but I looked in some magazines and saw a few trucks with the seat poking above the bottom of the window a few inches so I left it. I dont like the look of a seat being viewed from the outside but the seats are comfy on my back so they will stay. Maybe I am too picky on it I dont know...
