A daunting task, but for someone like yourself that knows the bike down to the connecting rod bolts, it should be fun. I've got a '61 A10 but it's all in one piece, just needs the valves adjusted and different handlebars - I told myself I'm not riding it again until I take the narrow SP-NT bars off of it that I thought I would like and put something else on ....
Good luck and good motivation!
