Sunpro mechanical guages. If you get a manual guage, spend a little extra & get an oil pressure guage with metal tubing from the guage to the sender boss. The plastic line will fatigue & break. It will blow a great deal of oil at speed. If you don't notice it immediately you could possibly ruin your engine. Luckily mine blew & sprayed oil on the windsheild as soon as it broke. Bought the better guage after that one.
