Hello kmenzel,
I ordered Side Cover Badges for a 73 750K2 some time ago from my local Honda dealer here in Canada.
They were only able to get those with the
Red jewel. Of course, it should be the
Orange jewels if you are looking for the correct replacement.
They don't look bad, as long as you don't mind. I eventually found an
Orange set on eBay last year. Think
I paid about $35 or $40 U.S. plus shipping. They do show up there from time to time.
Hope this helps.
Lou.
