Chris,
I would give CAMPER REPAIR CENTER in Montevallo, Al. at 205-665-2531 or
205-665-9501. This is an authorized Airstream dealer that has been in
business for several years. They have buildings full of salvaged parts. When
you ask for parts, he will give you new prices and used prices and let you
decide on which you want. It usually takes him a day or two to get back with
you on used parts. They get wrecked trailers in and strip all usable parts,
then recycle all of the scrap. They have no trailers new or used sitting on
the lot, mainly just a parts dealer on has good knowledge on the
trailers.They are listed in the WBCCI membership directory.
Hopes this helps.
Gary
