I have the 3.7 with the supplied gear adapter but I run 245 tires so my speedo reads fast. I need a .879 reducer or a couple of different gears.Sent from my U.S.Cellular© Smartphone

With the 3:70 -1 gears that I installed inmy 78 Royale with a 403 engine and original tire circumference, it is deadspot on the mark. Another option is a GPS speedometer, you just calibrateit as you travel down the road. Both systems work well.Jim HupySalem, OregonOn Mon, Nov 2, 2020, 7:30 AM 78gmcroyale via Gmclist wrote:>> Good Morning If I recall someone on here is knowledgeable of speedometer> gear adapters.
