I don't know how many of you know about this gauge offered by GM Sports Salvage. It is a new gauge made specifically for the square body light duty trucks that looks like the gauge found in the medium duty trucks. This allows you to keep your clock and have a tachometer (or any other small gauge you want in the lower left corner of your cluster). Their website wasn't too clear about the two different kinds they had, but thanks to Martin (@82355) here, they updated their website to indicate they offer this gauge in the early font style (1973-1979) and the later font style (1980-1991). The newer style is the only one pictured on their website still. I purchased the early font style for my build and thought I'd post a picture so everyone knows what it looks like. It looks very nice and matches the original gauges very well. My truck isn't at a point to test it, but I don't foresee any problems. You'll need to modify your cluster for this to fit by removing the warning light housing on the fuel gauge/tachometer side. It gets power by plugging in to the pins in the back of the cluster for the large fuel gauge then a wire goes out to the distributor/tachometer hook up.
