Fearing these scans will be too small, nevertheless I have something to share...
An obscure model car publication, this being Model Car Science. Issues to consider are the July 1970 and December 1971 copies. The July 1970 issue has a fine '69 Penske Donohue Camaro sans accessory decal markings and sporting period telemetry gear on the front hub - rather racy this. The July 1970 slot car build up is a bore, with no further period photos afforded. The December 1971 issue has quite a bit more, with some unseen photography from the initial race of the '70 season at Laguna Seca.
Check out the Chapparal Camaro front and rear lips in place before they were instructed upon technical inspection to remove the nonhomologated, albeit stock spoilers. In particular, I don't think this front spoiler was ever seen again, being replaced at some point with the heralded 'unbreakable Lexan' spoiler of much broader section to see the season out. The small rear spoiler was seen briefly at Dallas before the rain out, while I have a photograph which shows the #1 Camaro at speed presumably at a test wearing the same. No stripes on the rear spoiler, whereas cutouts for pins and refueling gear is noticed.
Very sorry I'm slow to understand why all this is so terribly small of scale and difficult to read, for I am not sure precisely what to do to improve matters. Anyhow, rather fun to examine in total. Thanks...
