Just to give you another option, if you are looking for something the same size, the 1969431 is the same but it requires a special nut and lock washer.
Which one is on it now, Alan? I'll check the ones I have and maybe I'll trade if I have the right one.
Adam, I have this pulley which is still on an alternator on my bench. 1961408 I believe this would be correct for a 1970.?? The pulley on the car is 1964758 which I think is correct for a 71.??
That size pulley with the stamp on it is pretty hard to find so I am reluctant to give it up. I'll PM you
This is the measurements you asked for. ss4825. I hope this can help you find one. This is for the 1852856 The 1969431 was superseded by the 852 (I think) so they are the same dimensions. The 431 requires a special nut and lock washer and is useless without them.It may be harder to find with the nut and washer included. It would be more expensive too.
Thanks everyone for looking you guys are great. Bubba Crouch found one on his bench and I'm good now. Thanks again,
