Tubular upper a-arms - Should I be worried?

I believe he was saying that they farmed out the work to some guy that can tig-weld CrMo and is associated with some NASCAR team (perhaps?). They are located north of Charlotte so that may hold water for now. While circle track cars do often have dedicated left and right suspension pieces, these were never advertised as such arms - simply as tubular arms that improved caster geometry and accepted stock style components. But the more I look at them, 'Jimbo' must have been jigging these at 3am after repairing a wrecked roll cage and was halfway through a 12-pack. I'm not prepared to start slandering yet, but they haven't responded quite as promptly as before so that may change if they don't take them back (or give me store credit as I am way out of the return grace period - my own fault). They should stand behind what they sell no matter how long it's been sitting on my shelf.

This company sells multiple make and model suspension/brake components and kits that they piece together from original manufacturers (and even advertise on this forum and all over the web). They apparently tried some custom fabrication stuff before I was wiser to the game and now no longer do that. At least those arms are definitely not on their site or eBay anymore if that's any indication...
