Not to derail more, but I just got my stuff back from Billmark plating. I sent in two sets of GEMS v8 fuel rails, clips, throttle linkages, engine lift brackets, and a bunch of radius arm washers. It was $100 for the plating. This is most of the parts
Here you can see the difference between new genuine radius arm washers, which appear to be yellow and silver zinc, and the cad plated ones. The cad plated parts have a much more pleasant appearance than yellow zinc. I always associate yellow zinc with Terra Firma, so I try to avoid it.
This plating turned out a little darker than I am used to, but I’m still happy with it. These parts were put on a 110 that I’m building to sell, so if it stays local I will report back after a year or so of use to see how it holds up.
