Calling V6 Third-gens

Im trying to put a Tachometer on ebay. i dont know the year of it and i'm having no luck finding it
Tach goes to 7000 redline is 6000 and yellow line is 5500... my tach redline in my camaro redlines at 5500 if you guys know when they started putting in a tach with a redline of 6000....or tell me what your redline is
thanks

On my firebird, the yellow starts at 5500 and the red at 6000

the 1992 had different gauges than the rest of the third-gens right?..its the normal round tachometer.....looks just like my 84' except for the redline...anybody else know anything?
