Just a heads-up to let you know you are in good company as a member of our Facebook group. Of our current 149 (and growing) members we have bragging rights to say we have the current editor of The Restorer magazine (Jim Spawn), a former editor of The Restorer magazine (me - 12 years), the editor of the Double A'er, publication of the Ford Model AA Truck Club (Neil Wilson), editor/publisher of Model A Times magazine (John Lavoy) and Jim Schild just joined us last night. Jim is the publisher of The Auto Review and is the author of several books in the Collector’s Originality Guide series, including Challenger and Barracuda 1970–1974, Chevrolet Camaro 1970–1981, and Ford Model A. Jim also wrote the book "AA Truck Supplement to Restorers Model A Shop Manual" so you're in good company here and between this "brain trust" we should be able to come up with some accurate info on AA's.
