Hey guys,
I've been on a quest recently to find a place to plate my suspension bits. There is no one in this area that is affordable so I have been calling all over the eastern seaboard. Anyway, I just spoke with this company in Lynchburg, VA and they sound promising.

Ask for, no joke, Johnny Cash.
They will do yellow zinc plating for $58 per Lot. A 'lot' varies but depends on the size of the parts. Small part lots are probably up to a couple hundred pieces. From what I could tell, our spring plates are classfied as small.
You can be setup as a COD customer and ship your stuff down there.
The only caveat is that they don't do any media blasting. He did say however that as long as the part is clean and fairly free of crud, it shouldn't be a problem.
So, there you go. I told they guy I would be posting their info for my 'car enthusiast friends' since we all seem to be looking for this service. I am not affiliated or anything like that. Just wanted to pass on what sounds like a good deal.
