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.

Kurt, I just measured mine with a micrometer and it right at 5.8.

Just checked again 5 3/4 maybe one small line over on tape measure. Original gm not repo.
