Anyone have (or even seen) a ’74-’75 dash with oil, temp and alternator gauges?

Pretty sure my factory manual and maybe even owner's manual (Haven't looked at them in a while.) shows full gauges as an available option on 1974 C Body gauge clusters.
My Sport Suburban only has a speedo and fuel gauge and I hate to hang one of those cheapo clusters under the dash.
If anyone has parted a full gauge cluster out and for sale please give me a heads up!
Also... Anyone know of any C Body specific salvage yards? I found one about fifteen years ago and can't remember where it was at... Nebraska?
Thanks!
