I have about 15 clusters worth of gauges, circuits, housings, and misc. pieces. All years/styles, from 73-91. All are used, pulled from local salvage yards. Condition ranges from near-mint to fair driver quality.
I have voltmeters, ammeters, temp gauges, fuel gauges, speedo heads, a few clocks, housings, circuit boards, PRDNL indicators, and tons of the little lens parts (turn signal/4WD/choke/etc). There are a few of the fiber optic ashtray lights in good shape. I dont have any really clear plastic lenses or good clean gauge bezels, but I have most of the other parts.
Post if you want anything and I will put up pics. I'm new around here, but I've been selling these on ebay for a couple years with good feedback. Ebay name "WasatchChevyParts"
