Topic: Grab rail for 1977 CB550K - Interchangability with other models ??

[kit_macdonald]

Greetings,

I'm new to the forum and am really glad it's here because I have a question regarding my '77 CB550K.  I'm looking for a new (or good used) rear grab bar and was wondering what other CB model grab rails are compatible with the 1977 and 1978 model CB550K, if any.  Also, if anybody has a good used one for this model I'm interested and have been checking ebay frequently.

I think the 77/78 model grab bar is specific, and not interchangable with earlier models.

Part no.'s:

77/78: 84100-404-670
75/76: 84101-374-670

Back when I was looking for luggage racks, which often bolt to the grab bar bolts, I recall them being model specific and not compatible either.

They are different - rear indicator stems, you can tell just by looking at the ones up for sale here --> http://search.ebay.com/search/search.dll?from=R40&satitle=cb550+grab+bar
