Dan,
I moved the seat back on both my Camaro and GTO....and its absolutely amazing! Look at my Camaro pics to see the bolted-in rails. Same as the GTO. Both these cars are extremely comfortable to drive now. The rails are bolted into the existing seat mount holes, so if you ever want to reverse it, just unbolt them and put the seats back in and its completely original again. This mod is well worth the effort for us tall guys. Completely transforms the driving experience. You'll never want it any other way again. Not much legroom behind the driver's seat left...but who cares? You could still move it up a little for the few times someone rides back there. I don't really haul anyone back there anyway. Besides, its MY car!
And, yes, I will call OPG. I really want that "wood" steering wheel. It will look awesome with the wood dash.
Thanks guys....
