IN 81-87 Chevy GMC Tach Cluster 4k Diesel

[Dave]

Nice 4000 rpm tach for 81-87 Chevy GMC truck equipped with a diesel. This will also work for a gas engine too. Cluster has no broken tabs and the printed circuit is good. 100 lb oil gauge. The instrument case in the lower left hand corner has a provision for a clock, air pressure or vacuum gauge (only on gas engines). Lens has minor scratches, otherwise good. Tach harness is mostly complete, brown wire goes to the distributor. Ask any question, thanks.
