Thanks for the input. I'm curious what other parts were zince plated also.
The other emissions parts? I'd like to get it all done at the same time as you
suggested.
Thanks again!

Hi Greg, If you go with zinc plating, originally it was yellow(chromate)
zinc. Caswell plating has a kit that works nicely, but if that's all
your going to do, it would be cheaper to have it done professionally. On
a 76, there's actually quite a few engine parts that were originally
yellow zinc, so you may want to have everything done at once. John
