Next, find a good place for the big yellow bottle. On our F-body, we chose to mount it on the floor of the rearmost storage compartment. Positioning the brackets is easiest if you assemble them to the bottle and measure where to drill the holes. If you trust our work, save yourself some time by using our dimensions. Dimension A is 31/8 inches, and dimension B is 63/4 inches, measured from the inner edges of the brackets. We placed them in position on the floor, marked the holes with a permanent marker, and drilled the eight holes. The brackets mount with the supplied nuts, bolts, and washers. We sure hope Hot Rod TV producer Kevin Oeste doesnt notice that we borrowed his drill.
