As of right now I have a 3 gauge pillar. On there are, oil pressure, water temperature, and N20 Pressure.

Now I gotta get the the gauge cluster, Im not putting a speedo siince there like 200 bucks. So Im getting the 1 5 inch gauge, and 4 2 5/8. Now the 5 inch is the RPM, the other ones I narrowed down to 2. A vaccumm, and a volt one. What else should I get? No fuel level either I dont wanna drop the tank...
