I was but a babe in 60's, the only affordable bikes and cars when I did come of age were from that era through. I used to fix'em up and pump them out, cars, bikes, lawnmower, whatever to keep the tank full and the bimbette de jour happy on the back of the bike. I remember most of them, many I'd like to forget (bikes and bimbetts.)
Here was one of my favorites, which I remember very well, a real ice breaker after a two up ride at redline.
It was a '68 or '69 "Grand Prix" 350, junked it after my gibblet head cousin borrowed it and blew the engine (ran it without 2 stroke juice.) I traded a 10 speed bike for it IIRC.
