I have a 03 Mobius LSV and I had recently purchased Perfect Pass for my boat and it was installed by a dealer. One problem though. They removed the calibration knob for the speedo they removed which the perfect pass display replaced. I would like to put a knob and whatever holds it in place so it doesn't look bad (hole in the intrument pannel). Does anyone know the part #'s for the knob and the part behind the knob that holds it in place. I understand it will have no function. It is for athetic purposes only. Any help would be appreciated.
