Hi. I sent a bunch of parts out to be plated and would like to know the correct plating for a few items.

Manifold vacuum switch - ZINC DICHROMATE
Throttle dashpot (damper) and bracket - ZINC DICHROMATE?
Choke heater tubes - ???
Throttle cable bracket - Black Zinc?
Throttle return spring - Clear Zinc?
Quadrajet to manifold mounting bolts - ???
Fuel inlet filter housing - ZINC DICHROMATE?
Oil Pressure sending unit - Clear Zinc?

Here is some pictures of the engine with the parts still installed.

I've searched the forums and found a few pictures which included what appeared to be an NOS throttle dashpot as well as an NOS vacuum switch both of which were plated with Zinc Dichromate. I saw a restoration thread showing the fuel inlet filter housing to also be Zinc Dichromate. I'm assuming these to be correct but wanted to put it out to the group for input. Any ideas on the other pieces here?

Thank you.
