Throttle cable mix up

[Siheinz]

Hello
I have tried ordering new cables for my UK spec 1990 600, and the company I am using are sending the wrong ones
my throttle housing has a cable that screws into the housing and one that clamps in

the company says that the 600 has cables that both clamp into the housing

I have looked at various microfiche online and they do look like they both clamp in?

I looked at the microfice for a 1990 fzr 1000 and the cables match the ones on my 600?

Very confused now why does my 600 have 1000 throttle cables and throttle housing?
