Default C4 Corvette Dash

Hello! I'm trying to figure out whether this dash is the one that came with the car or not since I'm having weird problems with the speedo and the tachometer ( the speedo keeps giving higher numbers than should while driving) (the tach doesnt work) the speedo will sometimes show numbers in idle as if it was showing the tachometers reading!!!
Also, the top oil press/coolant temp prompts don't switch with the drivers console (switches have been checked) Appreciate any help!

It is an early C4 dash, is it the specific one for your car, who knows? It looks like the polarizers are bad also

I'm sorry I should have been more specific.
I got an 85, and I wanted to know if this dash looked to be from an 85, or if it was another year's
Polarizers are good, is just bad pictures!!

Man I'm not the best at explaining stuff eh?
Nothing wrong with the pics, I just wanted to know if anyone recognized this dash to be from an 84,85,86 etc. Google shows me a lot of diff dashes for the same years.

Because I am trying to know if what is causing my problems(speedo showing wrong speed, also showing numbers while in idle as if it was acting like the tach) is the dash itself or something else (if I have the dash from a diff c4)

I even disassembled tbe dash but it looked completely fine, nothing burned out or anything.

That dash is NOT an 84 as the 84 had a different RPM curve and the center layouts were different.

Send your dash to batee.com and you will not regret it.
