does anyone know where I can finda new gauge cover (the plexiglass/ plastic plate) for a 92 ram?

 

Is the old one scratched or broken? you might be able to pick up a good used one with a cluster at www.car-part.com or
look on the old one for a part number...maybe 56003435? The dealer may still be able to get one? Try an online for a cheaper price.

 

If there's one nearby, try an auto salvage lot or auto junkyard.
