Title: 69 Z Smog Pump Pulley Diameter
Post by: KurtS on March 20, 2017, 08:43:51 PM

Anyone have an original smog pump pulley from a 69 Z that can measure the diameter of the pulley?  Pulley 3932458.

Thanks!

Thanks! Is it a little over 5 3/4? I only ask because 5.8 is a common size when I look at other smog pulleys.
