OK, been chasing this one for a while and was just curious if any of you know, is the correct 66 HiPo PCV part number C5AZ-6A666-A or C5AZ-6A666-A1, or something else entirely... every time I search I come up with different answers on all forums. And if for me we can be specific as to which would be correct for my Kar, February 66 build, San Jose plant.
Thanks as always,
Jason
