Slant Six power steering pulley

Well the pump came off of a 85 dodge D150 and I put it on my 82 dodge D150. I have hit up all my forums for Mopar parts. I just need that pulley pictured.

But the pic is from my buddies 73 Scamp

I have a 65 or 66 slant in the back garage that has a bad housing (the nipple is broke off for the return line), but has the pulley... But i'm not sure if it will work on an 80's vintage truck....
