Well i finally went out and bought a boost gauge for my 87 t-top GN and go figure it doesn't fit. I bought an Autometer Ultra-lite 0-35 psi boost gauge and the autometer single gauge pod. I put the gauge in the pod and went to test fit it on the a-pillar and it high centers on the corner of the gauge. Anyone have a sucessful installation with an ultra-lite series guage?? if so what gauge pod did you use? Are there any deeper quality pods out there? Any suggestions would be appreciated.
