Yawl, Installed the Dakota Digital gauges in the 51 and really like them. The model is the somewhat new VHX series. The install was easy and it all worked first try. Had one minor problem with a loose connection on the Dizzy to the tach. Replaced the connector and away it goes. Programming is straight forward and lots of options may be viewed. The process took a few days as I am not very good at working upside down under the dash. Can only work a couple of hours at a time. I do not work for or get any bucks for my words just a warm fuzzy feeling when I fire them up!!
