Welcome to the Forums coral! Migosh, where to start ... For broad research I'd probably say to look at the forums page (not the portal -- see at top left of this screen). On the forums page look at the breakdown of interest areas within the forums, especially the Restoration, Repair & Parts Forum. The Search function is a very good way to look for details -- you may get a lot of irrelevant returns but figuring out the best keywords in a given search will cut down on the browsing.
Thank you for joining in this Airstream adventure!
