Factory tach and speedo info.

Just bought a truck from my brother in law. It's a 79 swb 4x4. Has PS, PB, AC, tilt, cruise, dual tanks, factory tach, and pulse wipers. But I'm curious about the gauges. It has a 130mph speedo and a 7k rpm tach. I've never seen this combo before. Usually 85 or 100 mph and a 5k rpm tach.

I believe the 7k tachs are out of Camaros, maybe the speedo is as well.

GM never put a 7k tach in the 73-87 trucks. As mentioned its possible that it from a F body. They were similar and its a common swap.
