Power Steering Pulley Part Number and Pic Please?

[Gregski]

apologies, yet another pulley post...

so it's time to replace my belts on my beloved '71 GMC 350/350 however somehow I ended up with an odd ball part # 15390 39" length power steering belt, I believe the right length should be 35" hence part # 15350 (I like to use ACDELCO belts)

does anyone know of the proper power steering pulley part number so I can check mine (part # 3993341D M), my '71 came with all 73-87 Third Gen accessories all hodge podged together and I replaced them all with what I thought were proper Second Gen ones.

if it helps I am now running the two grove crank pulley (part # 3744043BA) and a two groove water pump pulley, (I deleted the factory AC) showing you some pics and part numbers

I will add the water pump and power steering pulley info in additional posts to keep the pics separate

I really appreciate your help guys,
Greg

Hi. You would need the 1232 p/s driver pulley bolted over your 0043 pulley. Looks like the pulley on your pump has a diameter that is too large. You will need the 3993325 pulley on the pump. At least this is how my 71 and 72's are set up.

Thank you so much Dude, you are indeed Super, ha ha... would you know if one of these pulleys is the right one, I don't recall which one I went with, one may be a Second Gen the other a Third Gen, or both could be wrong, might could go and check in a bit, didn't happen to see part numbers on these, sorry

The water pump pulley on mine ends in 646. It is a 2 groove.

The one on the left is not correct. Possibly the one on the right.
