Gauges

[b454rat]

I just found out the other day in a junkyard my buddy owns, he has a 61 Chevy, used to be an old tractor trailer style truck, so guessing a C60?? Anyways, it has the factory gauges along with a factory tach. The dash is the same as my 62 'burban, but will the gauges and stuff work in my truck?? I don't see why they wouldn't, but don't know alot about that sort of thing. If I decide not to use the gauges/tach, how much do they do for?? Could always use the extra money.....
