I bought corbeu racing seats and with the brackets they sell (seperate from the seats of course) it all bolts right in.. I removed my seat, bolted the brackets to the racing seats, and got the seat installed in about 2 hours(Took a while to figure out which way the brackets go, and then the seat belts were a pain to switch)... I bet if you knew what you were doing ahead of time you'd be able ot get it done in under an hour per seat.
i sold my summit racing seats, the rails they give u wont line up, ur better off saving another 400$ and buying two corbeau seats unless u can fabricate somthing
