NAPA auto parts have books on colors for 1987 trans ams.
you will need the ecm that goes with that motor, or have your ecm reprogramed but i dont know were you can have that done.
The 1987 Celebrity uses an electronic speedometer. There is a VSS(vehicle speed sensor) on the trans-axle that could have failed. The speedometer itself may have failed, the ECM (engine control module "computer") may have failed or there could be wiring issues.
It is the main computer box.
... what about it..?
1994 and 1995 lt1 both have a flash programable ecm they will interchange and can use cats tuner to reflash or tune it
If it has the same roof it should.
