just fab out your own floor, its not too tough, i've done a couple, the only hard part is getting the tranny hump right if you have a console....... if you're good with metal then just cut the old one out and build your new one as close as can be, make your own holes for the seat hardware and such and voila! that or if the chevy one fits just doesn't have the right holes then plug em and put the right holes in it
