I contacted the guy who is making a kit for mustangs to turn the stock gauges from vague and fake (oil pressure) into real, functioning and accurate gauges, and he said that he'd be up for doing it, but needs a [junk] instrument cluster.
he probably won't be able to get to it for a little while, but I thought I'd see if we couldn't get him a few samples to have so when he has time, we can get a kit for our trucks, eliminating possible redundancy (multiple gauges showing the same thing) and freeing up some gauge real estate.
For those wanting an interesting read, here is the thread about his work on the mustangs:
