You can expect to pay about 1k to have the gauges redone. Redline gaugeworks and aut-instruments do really awesome work. If you are worried about the correct parts for restoring the gauges then auto instruments is the way to go, but if you want the gauge internals modernized, then redline gaugeworks is the way to go. I have heard great things from both. When I do the rallye gauges in my challenger they are going to go to redline, and have the speedo redone to read 200 mph, and the tach to read 10k. Redline also normally takes longer than auto instruments, because they have less staff. So if you need it done quick auto instruments was faster, they were also cheaper as I recall. Hope this info helps. Good luck.
