Hey guys, I just got my '78 550 and need a little help with the gauges (among lots of other things). The previous owner had some mismatched terrible looking gauges on there, so I picked up some period correct ones from the junkyard. The only problem is that there is no sign of the little rubber pieces and the sockets for the lights for these gauges. I have just the gauges with no wiring. Can I source these missing electrical bits anywhere or am I SOL?
