I'm getting close to where I need to buy gauges and switches for the dash. I have a stock type Speedo' to install. To the left of the wheel there are two holes 2.5" or 2.25" I think. The PO hacked the hole on the right is for the ignition switch mounted on a small plate, The speedo has Temp and fuel gauges, so one of the extra holes should be Oil pressure and the other should be .... what? What brand / model gauges are "best value"? affordable and reliable.
