CodyPaul is right, there was an article in Sport Aviation. I just looked it up...very interesting! The aircraft was 3/4 scale and powered by a Lycoming O-435. The wing was aluminum; the fuselage was steel tube with aluminum formers and skins. The project was lead by a Mr. Don Roberts of Noblesville High School, Noblesville, Indiana. Construction began in the fall of 1972 and was completed in May of 1977. The article is titled "SBD 'Dauntless' Flies Again," and appeared in the December 1977 issue, pp. 31-33. If you are an EAA member, you can look up the article for free on the Members Only section of the web site. If you're not a member, you can get a copy by calling EAA. I've found them to be very helpful with requests like this.
A later article states that the Dauntless went to the San Diego Air Museum. This article, "Tora, Tora, Tora over Indiana," (May, 1987) describes another one of Mr. Roberts' class projects, a 5/8 scale Zero. It was mostly of wood construction, using the wing from the Cavalier and a fuselage made from a wood box covered with foam and fiberglass, similar to the WAR replicas. It was powered by an O-290-D2 from a Tri-Pacer. (Overhauled to "zero time," it says. Ha, ha.)
Mr. Roberts sounds like quite a guy. Per these articles, he built or rebuilt 10+ aircraft in the high school program he lead, involving hundreds of boys in the process. Our community could stand a few more people like him.
