Billed as a 68 missing parts, I bought it for the springer for a Grey Ghost project. When I got it home, imagine my surprise the springer is shorter than my krates (and the AS bolts). Bars say Schwinn, but no date stamp, gooseneck is a 66, I haven't pulled the sprocket and crank yet. Seat is wrong, but allows me to ride it. Serial Number is: A 25405. Frame is the same as my 71 Ghost. Any Idea what year?
