Not Ranked
I did a similar thing to what Blas described with the race car. I could not use the standard seats, had to have race approved seats, so I used some flat bar stock to keep the seat low, used large nuts as spacers so that I had room to work underneath the seat and used the existing holes and supports from the underside. I think that I may have had to drill one or two additional holes due to the race seat being of a different size and construction. But was still able to use the mounting supports.
