The sun is out which means play with the car time. I am changing the water pump and belt and have run into some strange pulleys. The part numbers are
Upper - 3900434 and Lower - 14037740. Can somebody tell me what they really fit.
Thanks
According to my parts book the 434 is for a 67-68 Corvett with A.I.R. (327) except Air Cond, Sp. H/Per. The other number does not appear to be a GM number. My book goes from 1938 to 1968 and almost all the crank pully numbers start with 3 and are seven digits long.
