I've been building a 1986 SR5 truck for a little over a year. I have run the VIN and it is definitely a SR5 model. (Bucket seats, chrome trim, factory sunroof, and originally EFI.)

The instrument cluster however does NOT have a tach. (Speedometer, fuel, and temp gauges only.)

Question: In 1986, was the instrument cluster with the tach optional even for the SR5 or has someone changed this dash out before I bought the truck?
