carburetor bodies

Does anyone know if the carburetor bodies on a 1973 cb500 are the same as on a 1974 cb550?
 
Attached is the best guide I have found so far and it is unfortunately incomplete or at least leaves info implied instead of explicitly stated. If you have any probs with the attachment, PM me.

If you look at the guide, the best I can say in answer to your question is 'I think so'. If it is of any help, the model number on those carbs is stamped on the carb flange that buts up against the carb side of the mounting plate, on the top right side of the carb flange. You will see 022A or 627A or whatever.

Later model PD46A carbs are not stamped there, instead its just above the float bowl, right side you'll see 46A and some other symbols, and those carbs are numbered 1-4, up on the carb body where the slide resides near the Keihin name.

Hope this helps. I have two sets of 627As, not sure what they are off. Also I need to know what carb model was used on the 74 350F (hoping it's 627A!!). If you find any info on these issues, please let me know.
