What he fails to mention however, is that none of those guys actually have interior door panels left on their cars... I think the Pro 2000 is the only seat that will fir without cutting the wings. Check out Sparco USA and there is a table of dimensions that may be helpful. It also takes a bit of work to mount them, as they do not match up to any of the stock locations, the Sparco slider bracket would have to be modified and the side to bottom mount bracket doesn't work either.
