I  have two 1950's that were donated to us, but someone was nasty enough to unscrew the shoulder nuts that make it possible for the server to hang on the rail. I need to order a dozen but I don't have a Dell part number.

Don't send me to RackSolutions, those people are thieves, they want $30+ for 12 nuts and $15 for Fedex home delivery shipping. 

If I can't order from Dell, does anyone have some discarded/damaged chassis from which those nuts could be unscrewed? Happy to pay shipping.
