I'll have to check. I know at work we send hydraulic cylinders that need their rods re-chromed to Motion Industries, but Motion doesn't do the chroming themselves. I'll have to see where they get it done.
Sorry, I don't know where. I just thought I'd reply because I'm a nice guy, and didn't want you to think I was ignoring you! Oh, and cause I'm a smart @$$! I'll see if I can find out anyone that does it though... I know some people that have done it themselves though... and I'll see how much they'd charge ya! what's it for? Your valve cover?
