Shader expert needed. My PRO glow shows through NGUI 2d graphics

I have a 3d object behind some NGUI 2d graphics. I’ve added the Pro glow effect to the camera and any part of the 3d object with it’s alpha on glows just like it should. Problem is the glow comes through the GUI stuff on top and I want it to be blocked by the 2d graphics on top.

Any ideas guys? Here is the NGUI shader that lets the glow show through… How would I change this shader to fix the problem?

Shader "Unlit/Transparent Colored" { Properties { _MainTex ("Base (RGB), Alpha (A)", 2D) = "white" {} }

    LOD 100
       "Queue" = "Transparent"
       "IgnoreProjector" = "True"
       "RenderType" = "Transparent"
       Cull Off
       Lighting Off
       ZWrite Off
       Fog { Mode Off }
       Offset -1, -1
       ColorMask RGB
       AlphaTest Greater .01
       Blend SrcAlpha OneMinusSrcAlpha
       ColorMaterial AmbientAndDiffuse
       SetTexture [_MainTex]
         Combine Texture * Primary
