Just wondering dose aftermarket seats bolt on to the stock sliding rails or do you have to weld them into place.. And do I have to look for a specific size of seat? I wanted to put some racing seats into my 67 coupe just wondering what I would have to do to get them in there?
If you don't mind spending a few bucks, Speedware Motorsports (http://www.speedwaremotorsports.com/) will make you a custom slider for the race seats that they sell. I installed a Recaro (purchased from Speedware) and had them make up a slider / mount assembly, and it worked with no fuss.
www.streetortrack.com and look up any of the corbeau seats. They have specific brackets/sliders which makes the seat install a bolt in. Im going with Forza's with one of their brackets.
