Hi, I posted this is the Heating and Cooling section but got no replies, so this might be a better place to ask.

I am confused about what pulleys are required when installing an aftermarket A/C system on a car that was originally non-A/C.

I am looking at installing a Vintage Air system in my 70 Judge and am not sure which pulleys, if any, need to be changed. I also will have power steering if that matters.

Do these aftermarket systems work with the stock non-A/C pulleys, or do I need to install the factory A/C pulleys?

If so, which pulleys are different and need to be replaced? Just the crank and water pump, or are the power steering and alternator pulleys different too?

Thanks for any help you can provide.
