I bought a set of aftermarket bucket seats for my gti about a year ago and have since sold the gti and want to put them in my nova(non bucket seat car). They already have sliders that bolt to the seats and the bottoms of the sliders have a few holes for bolting them to a bracket that are 12" front to back and 12" side to side. Does anyone know of a set of brackets like the procar brackets that are ready made to bolt up to the stock floor and the seat? Or does anyone know what the dimensions are for the procar brackets where they bolt to the seat?
