Built my own. some cardboard to make a template, <$15 in material from the steel supply place and a couple hours with my MIG. (incl install on the car) and yes mine protruded a little into the rear floor area, but not enuf that the padding and carpet won't hide; and I ain't sittin in the bcak of my own car anyway so even if it did I won't notice it once the car's back together!
