Have you ever seen the Rochester pull-offs with the front half in Silver/gray plastic? I'm thinking these were not true NOS but likely NORS.

Here are pictures. One is of the complete assembly, housing a silver choke pulloff,this number is correct for all non ram air 1969 4BC vehicles. The other is the 1970 only yellow pulloff.I could not find the box, it is here somewhere, but I have over 1000 NOS parts in my shop and am not going to spend anymore time looking for it. As you can see, the silver one's are real,unless you believe the metal part is repo also, as well as the shaft being painted green-as they were back in the day..
