Considering how very little is directly interchangeable between the 250 & 450 Rebels --- which were available at the same time --- I wouldn't hold my hopes up for an early 80's model compatibility with a model that debuted a decade later. Especially a model that utilized the CM/CMX 250 engine no less, instead of the Nighthawk I4 platform that sailed under the CB designation.
Seriously, much like the Rebels they probably don't share much more than a marketing name.
"Ride Safe, Chop Safer" Motorcycles are not unsafe. However; they are extremely unforgiving of inattention, incompetence, ignorance, and stupidity.
Dismantling, sawzalling, and rattle canning does not make a bobber.
Those are STEPS toward customizing, not customizing unto itself.
