i put the gaffrig gauges in my 21 bahner... which back then were originally made by Livorsi... (then they split up, livorsi made their own label, and gaffrig had to change their wording...)

(still waiting for my fuel level gauges to come in... sigh ebay...)
i DO have another set of gaffrig gauges, minus the speedo... $100. (guy i bought em from had twins in his boat)

the tach has an hourmeter built into it.
