Factory vs. nos pulley's
 

Im looking for pulley's for my 67 BB camaro. Some just have the part# and some have part# and two letters. What one are the factory pulley's? On CRG they list the pulley part#'s, but no two letter codes.

I put the 67-68 pulley list together years ago. I have 2 letter codes for most of them. Some of the early pulleys have no two letter codes. I don't think the 67 1-groove water pump pulley had them. What pulleys are you looking for? Martin

The water pump 3905995, some on ebay have CF and some have no letters. For L-35 w/o smog no p/s. And the 3874412 is just a single groove? 3909815, AJ OR no letters?

You need to check with original 67 car owners to see if the '5995 has the codes stamped or not. I seem to remember no for 67. Does the Assembly Manual show a spacer behind it? Yes, the 3874412 is a single groove stamped steel pulley. My notes say the code is A. And the alternator pulley is part of the fan. My notes say no code but I don't remember ever seeing one. Sorry that's all I can help with. Martin

I have one each of: no part number, part number and part number with CF code. Any original owner 67's?

Yes, i would like to see what a 67 camaro original low mile L-35 has for pulley #'s. Anybody? Also some are painted black, and others are phosphate.
