i used my factory seat brackets, measured then redrilled and tapped the bases of the aftermarket seats..... drivers is perfect but i f'ed up the passenger a little and made it to narrow... il take it back out and redo it one of these days..... the drivers ide is the easiest since its got all the power stuff... having a power lifting and sliding seat is sweetness....
i am using a sparco manual bracket and sliders....but its being a bitch...the frustration was bugging me last night during the install so i just went to sleep....saturday morning=Part 2
make sure you get the bracketts for your car instead of the universal ones, that might be the source of your problem. I have the corbeau fx1 pro seats, and the mounting brackets from corbeau as well. They went in with no problem what-so-ever.
