Wow did I stump the board? These are the part numbers I cam up with for a 3 groove water pump pulley for 1967 and 1968, I think they are SB part numbers. They are 1967-3906657 DP and 1968-3908920 DQ.
This was the motor I found on e-bay out of a 68 L79 corvette but it doesn't have AC. As you can see it has the 3 groove pulley.I will get some more pictures of the bracket this weekend bolted back onto the motor. The idler pulley is what has got me stumped? In my picture I posted of my motor it looks like the idler pulley is behind the AC compressor. So it must be part of the smog?
