60-66,

With the holidays over late for us as our son had the after Christmas leave schedule this year, he got home Dec 31. I am just now getting back to 1964, K10 project.

Currently looking for the part number for the 292 engine PS pulley.
My master parts book does no show a number for the pulley until 1966 in group 6.655. I think the number for 1966 was "3791943 except 292"?? and "3906398 for 67 up".
I am hoping you can help me out with the part number and/or number cast in the pulley. Thanks again for the greatly appreciated pictures of your 63 pulley, along with supporting information. Did you ever find out more about the uniqueness of these pullies?

Thanks
Les
