Help verifying part numbers for power steering upgrade

Quick question, I've decided on the parts I'm going with for my power steering set up but just wanted to confirm the part numbers. This is for a 93 4.0HO XJ w/ AC

For the pump I'm going with the PSC pump # PSC-SP1215

I want to add the under drive pulley (this is where I get stuck) # PP-2411 is what I believe but can't confirm

I know I will need a new belt with the smaller pulley anyone have a part #?

The lines,cooler and filter I already have verified

Any help is appreciated

Thanks

If your going to get a psc pump why don't you just get it with the undersized pully. I would imagine they sell it too. I don't know of any option for an undersized pully, but I'm doing the hydro assist using the stock pump and pully to beef up my steering.

Pp2401 is the part number iirc

But if your ordering their pump, just call and ask. They'll take care of Ya!
