I am reading the original hand written order sheet dated oct, 16, 1969 from Cartelli Pontiac out of Holyoke Mass, which is signed by the salesman and the original purhaser of my 1970 gto conv, 455, 4 speed car. The order sheet clearly states as one of the options "exhaust D.C." price $63.14. Correct me if I am wrong is this the Humbler or tiger button exhaust option? I believe it is. The car was delivered without the option, any one care to speculate as of why. It was ordered and paid for. One theory is pontiac stopped making it at that time. Any input woud be greatly appreciated. If it is what I believe it to be, would it be wrong or incorrect to add this option now, since it was originally ordered with it? The car was also ordered with what is listed as a foam steering wheel, price $42.13, (Formula wheel?) also not delivered what gives?
