I have the trio of sport comp gauges that was in my Duster. The Amp gauge was installed but never hooked up. The water temp & oil pressure gauges are mechanical. Both worked great at the time of the accident. The oil gauge was hooked up with the nylon line that came with it but I cut it off at the gauge. The water temp comes with the sender hooked up & has the fittings for it. Located in whittier. Also comes with the 3 gauge mounting bracket. Asking $60 obo for the set.
