This is a long shot... but I'm looking for an older, discontinued Defi Boost Gauge.

Defi Link Meter, White Face, Green Illumination - BAR or PSI - I'm open to either. I'm after 52mm but may entertain 60mm. I will also need the control unit (Defi-Link Control Unit II or Defi-Link Control Unit) to go along with it - not a deal breaker if you don't have one.

Maybe someone has one kicking around they removed? I used to have one 10+ years ago... wish I held onto it.
