Here is the info on the plater, I used for my parts, but there is some details you should know . Moore metal Finishing, located in Toledo Ohio, did the plating. I took in 2 sheave halves, 2 starter block off plates and the hardware to my brake caliper. They did it all for $10, lunch money as they called it. So if you go there, it is cash only, no checks, and no credit, or debit cards, cash only. They are more than willing to take walk ins, as they like to have free lunches, that seemed to be the theme of my visit.
I would also recommend you do some prep work before taking in any parts. They do a good job with cleaning off dirt, oil and grease but they don't do anything with rust, and they won't touch anything with paint on it. The inside of my sheaves had some surface rust on them, and even thought the plating covers the rust, the surface is still rough looking from the rust. So a little prep and you will have some excellent looking parts, at little expense to you. I also asked whether they would accept parts that are shipped to them, and they said in some cases they do. If you have some parts that you want to ship, you can give them a call and talk to them about it. They are very nice people, and were more than willing to help me with my plating. I'm not sure what the going rate on plating is, but $10 seemed pretty cheap to me. I will be going back that's for sure.
The parts I had plated were done in yellow zinc dichromate, which isn't an exact match to the original, but I don't think that method (cadmium) is done any more. They also do zinc nickel chromate, silver looking, and black zinc dichromate. Here is the address for their website, so you can take a look.

The pictures above don't do it justice, I was using a camera phone, which doesn't have the best resolution. The color is much brighter when you see them in person, and there is some blue in the plating, but they still look great, much better than painting them, like I did on my 77 Liquifire. I will be redoing those next summer for sure.
