CB750 K1 Float Bowls

[Sparky]

Hi, hoping a more knowledgeable person than me can advise...
I've just stripped my carbs down on my 1970 USA K1 and found the overflow brass tube broken off in float bowl on number 2 and some numpty has pinched the output and then stuck the overflow tube back on!!
So needing a new float bowl, have looked at CMSL website and they show 2 versions according to serial number. Mine is the earlier (frame no 1061605) and typically is far more expensive (£178) - the later bowl looks nearly identical and is only £25.
Does anyone know if I can get away with using the later variant - weblink for reference - https://www.cmsnl.com/en-gb/honda-cb750k1-four-1970-1971-usa_model14354/partslist/E26.html

Thanks in advance

Sorry, should have added - are early K1 carbs same as all K0's?
This gives me a chance to find second hand on Ebay

K1 carbs are different to the earlier CB750 (K0) type - that said, the early type K1 float bowls  are the same as the earlier K0 type.
Difference between early / late K1 bowls is the drain screw - small screw head with aluminium washer on early, larger screw head with o-ring seal on later ones. The bowls are interchangeable as the carb bodies theirselves are the same an all K1 and will be marked 7A on the top of the mounting flange.
So, buy the cheaper NOS bowl or find a used one of any k series bike up to the K6.
