Hate to not add anything beneficial, but I experienced a VERY similar problem with these guys. Ordered the idler arm brace, got no update for a week, called them. I was told it was at the powder coater will ship out the next couple days. I don't get an update on shipping the next two days and now it's the weekend so I can't contact them. Call them first thing Monday, they tell me it's still at the powder coater and will ship the next day. Finally it ships that Wednesday. So two and a half weeks after I ordered something I was told was in stock ready to ship, I finally have my little idler arm brace after having to call them TWICE regarding the stupid thing.
While they were responsive for me, it seems like, "It's at the powder coater." is a diversion tactic in the vein of, "Oh, someone other than us is taking a long time to finish your product our piece is done." Some folks seem to have great luck with them, though, and from what I've read they always seem to deliver, even if it is late. It's just the process that's like chewing aluminum foil.
