I have this older mechanical VDO gauge I no longer need. It has a 30 lb face, and I checked that the lamp still works. You'll need to round up a boost line kit, but that's no biggie. I used it in the pod I have pictured ... I used two small #4 screws to attach the pod to my B pillar, hence the two holes. Both are available. I'd ask $35 shipped to your door for the gauge, and $50 if you want both parts. Let me know ... Best to PM me.
