Seat Brackets for Racing Seat

Got a racing seat recently and it has the crappy universal seat brackets and I was wanting to know if anybody has used these Mantaray Motorsports Seat Brackets? Also are the sc2 Seat brackets the same as the sl2 seat brackets? Last If none of these work how could i go about getting an SL2 Seat bracket to fit.

Thanks,
Paul

I can't understand how the sl2 seat brackets couldn't be the same as the sc2 brackets; GM typically uses the same small parts like brackets on many models. i haven't messed with my seats yet (don't plan to get racing seats till summer) so i don't know how they look or anything. Sorry i couldn't be more helpful.
