The engine fits like a dream. with the stock carb the choke lever hits a little on the top tube, but you can still turn it on and off. and the wheels on the cranbrooks are good, with some work. they need to be trued from the store, which isnt too big of deal, since they are wide rims with thick spokes. you will need to repack the hubs and there wasnt much grease in them. And replace the coaster hub bearings, the stock ones in my hub were soft and blew out in a short time. i put in some shimano bearings from the local bike shop and it was fine. The rims will not work well with rim brakes, you might be able to use one of them disc adaptors, or make your own for up front, the flanges are pretty large. you could drill and bolt a disc sprocket to it, maybe.
