Hopefully some of the Denver crew will chime in. I know Jon (VXorado) used to know a welder, and may still have someone that he works with.
If you do wait until Monday to head to Moab I can get you in touch with the shop that did my front bumber. The build tube buggies and I know that they can weld anything up, but they are in Rifle, Colorado which is three and a half to four hours past Denver toward Moab.
If you do make it all the way to Moab, I know that there are MANY fab shops there that could weld that up lickity-split.
