So, I am working on mounting a York 210 Compressor for my bag setup. Need to find a water pump pulley that has dual groove pulley so I can run a 2nd belt to compressor. '58 235. Dimensions on current pulley are 3 1/2" deep, 7" diameter, 1 7/8" bolt pattern. And those are my dimensions measuring it on the car. Don't know what other pulleys for other car that would be in the general size range that could work. Not opposed to doing a bit of modifications. Just don't know where to start looking. Also not opposed to a dual groove alternator pulley, if someone could point me in the right direction. Any help is greatly appreciated.
e-mail me a close up pic of your current lower pulley and I'll find you something in a chrome aftermarket.
