Well, the guy that mucked up my engine with his robo wrist told me it was an apache series. GM Vintage and Bluebird cannot trace the numbers ex V.I.N Factory etc. They are stumped as well. Soooo I guess the hood is after the 66 apache truck ? Can I just get on with this !!??....lol. Anyways I need a 63 manual with a 66 supplement manual I was told by GM Vintage. Ok,...this is where I drink every drop of booze in the house on the hood of the bus and watch the stars till the crows peck out my eyes in the morning. zzzzzz zzzz zzzzzzzzzzzzzzzzzzz
