I pretty much has the same exact seats and i know my mounts are identical. I have the fronts at the bottom setting and the rears at the second setting and still using my seat pans. Mine came with mounts already for a older camaro. The rear bar that connects the seat i mounted directly the seat pan by drilling a hole where i wanted the seat positioned and then added tabs the the front.
My seat brackets look like this

I removed the tabs where it would normally mount and did just like i said above. Im 6'2 and i have plenty of head room, and leg room.
