Thanks for your reply. I believe in order to put a ram-air '66 back to its original or stock form, i believe i need the following: heavy duty fan, 4spd close-ratio, 4.33:1 gearing, metallic-lined brakes, not to mention if there is any info on the color of these 50 cars that came from the factory! If an A/C package was available. I guess my goal, (which maybe impossible) is to put a car back to exactly like it was in '66. Its been 21 yrs. since i owned a gto, ('67 335hp car), and i have a chance to get back into this wonderful world of gto cars. Now if this car is to be done, i wouldn't build it for myself, (to much power for me and to many rare parts). I'm looking for a nice crusier '65, or '66 335hp car). I would think there is a collector out there who would be interested, thus the importance of the above list of items. The only problem would be once finished i don't know if my wife has enough strength to pry my hands from it! Thanks.
