I am looking for a set of three pulleys, Crankshaft, Water Pump, and Alternator.

I need only the pulleys. My engine has an R4 AC compressor mounted low on drivers side. Power steering pump mounted above that.
My 1980 and 1983 SD are so similar I am assuming just a set of pulleys will allow me to put double belts on
water pump , alternator, crank on the 1980 300D.

From a 617 engine in a diesel. Not sure which years will work, but
I know for sure a 1983 will, so let's start there.

Probably any 1981 to 1985 will do.

What I specifically want is the double belt version of the alternator/water pump/crankshaft.

Shipping to zip code 93551 in the USA.
