I've heard of that happening with C3 Vettes too Keith. Guys sometimes find the build sheet under the carpet when doing a replacement and quite often it will be for a different car. I would think the tank sticker would be accurate as it was glued on in the later years. I just find it interesting to research these things. I haven't gone looking for the tank sticker on mine. I do have the package from GM Oshawa that gives me all of the RPO codes for mine and some of the production figures for cars imported to Canada. There were 2,827 Corvettes sold in Canada in 1975 and of that, 1067 had air (C60) and 2,500 had the L48. I guess there were only 327 L82's that year if I do the math. Whomever ordered mine didn't spring for the Tilt & Tele but did get air (C60), PS (N41), PB (J50), PW (A31), rear defrost (C50), dual horns (U05), AM/FM (U69), automatic (M40), 3.08 axle (GU4) and white wall tires (QRM). I don't have the Canadian production figures for those options.
