kehin OE carbs jet question

I just rebuilt my 75 kz400 OE Kehin carbs with all new jets. Only jet my kit did not come with was the top slow jet 35. I got the bottom one with the emulsifier tube attached just not the one that goes on top of it. Anyone know where i can buy one from?

What's wrong with the original jet? Unless the jets are damaged it's typically better to reuse the original OEM Japanese jets/brass parts after cleaning as opposed to replacing them with aftermarket parts.
