I'd like to raise the driver's seat approx. 1". Haines notwithstanding, only the two front bolts and left rear bolt point down so that one can easily add shims. The right rear bolt is horizontal, screwed into the hump in the middle. Is there only one horizontal screw hole under the carpet? Or is there a higher one? Any advice to raise my (simple, not motorized) driver's seat?
Thanks! H.K.
