i found a bike up in the rafters of my dad's garage last week, a CCM 2speed Genuine Mustang Cheetah, and i'm currently restoring it. however, i can't, for the life of me, figure out what year it was made in. i'm pretty sure it's vintage, and it seems to have all of it's original parts. anyways, this bike really has the potential to be a really sexy ride, so if anyone here can tell me what year this bike is, i'd be forever grateful!!!! thanks so much in advance!!!
