Is there any way to use racing belts (i.e. Simpson, G-Force, etc.) with stock seats? If I have to get seats also I'll get some good ones but I really don't want to fork out $600-$800 bucks for seats. How do the ones that aren't roll bar mounted bolted on anyway? On the back of the seat or something? I have a new motor ready to drop in and it MIGHT get me to the 12's, which is racing belt time according to NHRA rules I think, it will be close. It'll probably be slower, LOL.
