There's a metal shop here in town that does fantastic work, so I am told by a fellow vintage AS'er with discriminating taste. I haven't used them just yet as I haven't had the need but will definately give them a call when the need arises. The shop is Warden's and they can be reached at 480.966.4675 or through email at: email@example.com
. They also have a website - http://www.wardensinc.com
Good luck and let us know how it goes.
