vt-7 had a 18x8.5x8 front tire and a 21x12x8 rear tire, vt-3 and vt-5 had a 18x8.5x8 rear tire with a 15x6x6 front tire and a vt-2 and vt-2c had a 15x6x6 front and back tire. vt-7 also had the rear fender mount welded to the frame and the vt-2,3,5 all had a bracket coming up from the shock mount area up and over the tire for mounting the fender. Hope this will help you out. I'm restoring a vt-2c and a vt-7 right now and plan on restoing a vt-8 and vt-3 later on (next year) ,looking for a vt-5 right now. Also the vt-5 and vt-8 were never painted blue, some early vt-2c's were painted blue but most were red late 1971 and up
