NOS Throttle valves

[Z.O.A]

I've come across a full set of genuine nos throttle valves with the P/N- 16025.1009 (listed for Z1R in Kawasaki parts list) and another set of two with P/N- 16025.085 (Z1000 A1, Z1000A2, etc).
The throttle valves for my A4 are P/N- 16025-075.
All of these throttle valves have the same cutaway of 1.5 and look to be the same, I know there were various differences in the carbs, but as far as I know the only change in the throttle valves was the cutaway.

I was hoping someone here could say for definite if these throttle valves would be directly interchangable with the existing ones in the vm26sc's on my A4 , if so then I will nab a set.

Thanks in advance for any info.
