You are right Frank.
This airbox sat on my K6.

Im not sure what’s wrong with air box?
Please enlighten me

My error I see that the air box is for a CB750 F but rear shocks look correct 
black body? Thought 70-76 shocks all the same all chrome bodies and springs
70 and 71 had a black inner body and the round aluminum top attachment to the frame was black also. You can kind of see it in this bone stock unmolested K1 of mine but a close-up pic would show it better. This other brown one still has the 'black' shocks also.

Those are very nice original k1's.  Hard to find these days and they are appreciating because k0's are getting too expensive. 

Excellent observation regarding the shocks.  I had to run out to the garage and check for myself.  I have an early k1 and a late k1.  4/71 has the black type clevis shock and the later 9/71 has the regular aluminum type.  I never noticed that before.
