Need help pulleys on AC 340

What's your set-up? Post some pictures...

You're trying to mix and match new and old...

the 67 used the cast iron water pump and had timing marks on the pass side.

70 and later used an aluminum water pump and timing marks on the driver's side.

70 and later used a double pulley for the a/c, alt, and fan.

67 used a single belt/pulley for the a/c and had an idler pulley to tighten the belt.
