I have a cast (aftermarket) crank pulley available. It is a three-sheave for water pump-alternator, water pump-power steering, and air conditioning. The air conditioning belt crosses the crankshaft pulley, an idler pulley, and the a/c compressor.
I also have a two-sheave (original '67 Ford) water pump pulley for the above.
The alternator offset is adjusted by the length of the spacer and the placement of the alternator bracket that also requires a small spacer.
When I aligned mine, the radiator was out and I used a carpenter's square to align and set the pulleys. Basically, I put the square across the front of the crankshaft pulley and used this as reference for spacing the other pulleys. It worked out fine.
As I said, you can likely get a set of matching pulleys from Classic Auto Air in Tampa, FL. Just search on Classic Auto Air and their phone number should pop up. If you can't find it, I will look it up for you.
