Guys, I can’t thank you enough for your help.

So here is my dilemma, I’m looking at the CRG site under 67 Camaro pulley configurations and according to that I have the correct pulleys for L78 w/smog.

3863108 Crank pulley
3906656 Water pump pulley
3880800 Smog pulley

The crank and water pump pulleys are 2 groove, with the smog pump mounted it appears it needs 3 groove pulleys on the crank and water pump in order to work? What as I missing here?

Also, when I bolt up the bracket that would tighten the belt, assembly manual shows it mounts from water pump stud to the pump, well when it’s mounted like that the Alt belt hits the bracket? The bracket I have (67 only I believe) looks to be correct according to the manual.

I’ve dug around quite a bit looking for info and pics for this setup and there is not much that I can find. 68 /69 much more info out there….hmmph….
