Fox 36x (NVA) Needle Valve Assembly

[Mack Lewis Jr]

I need two Fox NVA's for Fox 36X. Fox Manufacturing does not have them. I understand that a ST 21 will fit, but I am not able to get these either.  Can anyone help me with this.

Thanks
Mack

If I'm not too far off, The small ST NVA that fits the plain bearing 35 and the G51S and the G34 will fit it. If not, RSM and Stuka Stunt has the G21 copies.

   The Super Tigre G21-35 (any of the G21 series) should fit with no filing nor shimming.  We used to use them in combat on our Fox series 35 and 36 Xs.
  The others are a little short and require filing off the bumps on the sides of the venturi of the Fox engines.
