replacing outer gauge rim
 

The top of my gauge got melted in the "spark" accident. Should I replace the whole gauge cluster or do you think I can find just the outer plastic piece that is shown in the OEM schematic?

Here's the part.

Guage replacement
 

My guage assembly is all one part. Molded together. No screw holes in my guages like the one shown in link.
