Does anyone know of a place that fabs seat mount brackets to move the dr. seat back a couple inches for more leg room? I got a set a long time ago for my 67 camaro, but have no idea where I got them from. The ones I have look like a piece of steel U chanel about 2 inched with with the sides coming up maybe 1/2 inch. The mounting holes are drilled and thre is a set if square nuts welded in from underneat and back a couple inches then from the original mounting holes, thus putting the seat rearwards that couple inches while the bracket then bolts to original factory seat holes...Anyone????
