I have an 88 and I am missing the maintainance schedule book and the G.M. protection plan with vehicle i.d. card. I have tried the Corvette museum, Chevrolet, E-bay,the origonal owner and no one can help. Any ideas would be appreciated.I plan on having the car judged and I need these for this purpose.Does any one know who printed these item's for G.M.? If so how I can contact them and get some help?
