Hi, I went to http://www.egauges.com and went with the VDO Cockpit Royal group as that group had a oil temperature gauge. I e-mailed the co. and told them what kit car on what doner car I had and they responded with the sender numbers to match the chosen gauges. I have a speedometer, tach, volt, fuel, and oil temp gauges on the way. Haven’t seen them yet as I am not home this week. I wanted a clock also and went with the Autometer Old Tyme white. I wanted a 90-95 mph speedometer, but none was available in the style and size I wanted. The speedometer and tach I bought are 3 1/8″ dia. as the holes in the dash are 3″, and I didn’t want the hassle of opening them up to 3 3/8″ or 5″. Hope this helps, Rollie
