My engine came out of a 74 riviera. I was busy blasting and painting parts the other day and I notice the power steering pulley has a dent in it crushing the pulley groove a little bit. The pulley has the part number 1377638 stamped on it. I have been doing a bit of a search for it and can't locate that part number anywhere. Any suggestions as to where I can find a replacement pulley? Even most PS reservoirs come without pulleys so I can't even just buy an assembly. Thanks Jon Fast forward a couple hours and.... I was able to give it a minor adjustment with a hammer to get it fairly close, and then I turned a spud, mounted it on the true center and was able to turn off just a little bit off one side of the belt groove to get it so the max runout is at .005" on one side of groove and .002 on other side of groove. I have to think that is close enough for the belt to ride accurately. Thanks for anybody that pondered this.
