Hello All,
I am at the tail end of a 216-235 Engine Swap. A machinist friend will be shortening the water pump shaft for me. Can anyone tell me where I can locate the correct short pulley? I have tried calling and emailing Jim Carters but cannot seem to get thru. They provide it with the water pump but they do not appear to sell them separately. Classicchevy.com has one but they are unable to tell me the groove width. The groove on the HB pulley is 5/8.
Thanks!

Patrick
