Sendo, that looks exactly (except for the snazzy chrome finish) like the one I used when I installed the Classic Auto Air system in my 402 '70. I simply cleaned repainted an original 3-groove pulley that I picked up at a swap meet for $5. I am not in the same location as my '70 454 with factory A/C right now so I can't check that pulley or belt configuration but the 1970 Assembly Manual shows the following belt configuration for the crank pulley: the alternator runs on the larger outboard groove and the water pump pulley; the power steering pump runs in the center groove; and the A/C runs on the inboard groove. If you don't already have one, I strongly suggest you get the 1970 Chevelle/El Camino/Monte Carlo Factory Assembly Instruction Manual. It will be invaluable for the project you are doing and many others. You can get one on eBay at this LINK. See page 160 for belt configuration and pages 450- 517 for RPO C60 air conditioning. Good luck.
