69 Z28 - Smog Pulley # 3932458
 
Hi Guys,

Can someone tell me the difference between the 69 Z28 Smog Pulley P/N 3932458 and 3932458DA. I need to get one for my Z.

Thanks,
Dave

the 458 is a deep groove pulley which would be correct for a 69 z-28

At least 2 versions of the 458 pulley.

Original equipment had a hard-stamp part number and were grey or black phosphate. Later service replacements were painted black and had an ink-stamped part number.

My 74 z/28 has its original and its the ink stamp variety.

That leads to another question.

Would the 74 water pump pulley and crank pulley have been ink stamped too, or been stamped with a number punch?
