Honda-SOHC

Hi all, stripped the carbs (657A LB designation) today to find that no1 was badly damaged with a crack on the air side. As soon as I touched it off it came in my hand      Could anybody tell me if no1 is the same as no3. Also my bike being a K3 is this carb the same as K1-K6, I have seen a few on Ebay but they look pretty rough but once vapour blasted and cleaned should look okay. Anybody got a spare they don't need and would like to be free of or could recommend the best place to source a new or used body. Or would the body still be useable with this piece missing as the rubber still clamps securely. See picture.

Hi all new here so be kind....
Just got my CB750 K3 and want it back to an original colour. The colour I like is  flake sunrise orange. I would like help with the side covers they have been filled where the recess should be for the emblems. The only new covers I can find have the recesses for both emblems the wing and the 750 four which would not be the correct emblem. So my problem is should I stick with the original 750 four emblem or change to the earlier one that sits in the recess not on top. Also what should the colour of the Honda wing be gold or red?
