Non-AC Water Pump Pulley AC Crank Pulley

I have a 70 Challenger with factory AC. The AC is not working and I want to remove that mongo compressor. Bought a non-AC pulley but the diameter is larger than the AC pulley and it hits the crank pulley.

I cannot find a smaller diameter pulley with the 3” drop needed to align with the alternator. I do not want to change the crank pulley since I will be putting AC in it in the future.

Anybody know what would work and where I can buy it?
