Default OS Needle Valve question

Hi Baxter, I have an OS 70 SZ I am going to use in a fuselage. and I want to use Allen wrenches for extensions on both Needle Valves, are there Airplane Engine Needles I can use to replace the SZ Needles ?? I need them for both the High speed and Mid range.

thank you Baxter !!

A good reason to save wheel collar wrenches. That is what I use The flat faces prevent slippping

"Allen wrenches" yes,, but the Needles on a Heli engine do not have Set Screws to hold the wrench in, too add the needles I have that are for OS Plane engines use a different "Taper" on the Needle than the OS 70SZ Heli has, this is why I asked
