Check out my photobucket site,
http://s90.photobucket.com/albums/k257/2blu442/ on page two I have some different wheels shown. The 1968 14X6 won't fit disc, but the newer 1970's-80's 14X6 and 14X7 will, plus the 15X7 will. Also, it would help if you posted the city and state you live in, who knows there may be another Olds guy right across town who could show you wheels in person if he knew where you were.
