Thank you for the referral to Sunny Hare. He was so informative and as you said great to work with.
They have been in business there since 1954
, and have a close relationship with the Airstream factory. If you need anything they are probably the people to know. They specialize in heavy construction (rebuilding Airstreams' exteriors after accidents).
I found out one thing, weep hole covers are not a discontinued part. These come in two sizes from the Airstream factory (1.75 "flat" and 2.5 inches "screened"). It sounds like they sell out of them regularly, but get a steady supply from the factory.
