A little more progress, removed the red screen from the kombo gauge to install the 911 temp gauge. The gauge pod and temp insert are a direct swap, the only real difference is that on the 914 the gauges are arrange on top and bottom whereas on the 911 they are side by side. The 356 shares the top / bottom orientation and has similar warning light locations so I will use the 914 pod and fascia. One interesting thing that I noticed when I removed the gauge was that hidden behind the fascia at the very top of the gauge face there are numerical temperature graduations. evidently 150 is regarded as too hot (the beginning of the red zone). The 911 style white bars will be replaced with the early style 356 green numerical style when I redo the faces.
