This K1 has the same brake peddle and has the tag on the frame for a bolt. As seen here number 16 > http://www.cmsnl.com/honda-cb750k1-england_model14355/partslist/F17.html#results

Hmm I went of the Genuine Honda Parts Manuals link  I have posted millions of times on here. Scroll down past K3 onwards to K,K1 &K2 parts manuals for a comparison of the early models

Perhaps yours is a very late K1.  CMSNL parts list are great generally but they sometimes have errors in my experience.
whatever, it seems to be the correct bolt for the later bikes fitted with it.

Bitsa, Do not mention that word 

Ash, i even have it on the microfiche for a UK K1. And the bracket that it goes through is on the frame. Confussing
