I'm looking at a 1976 cb500t basket case, mostly for the disc brake front end to use on my 1974 cl450. Are any other major parts interchangable? Mostly I'm thinking engine parts, since I haven't opened mine up yet and don't know the condition of things like the cam chain tensioners. The 500 is dirt cheap, with a title, but I'm not looking for another project, just parts for the 450. Should I buy it?
