My instrument cluster is fine, but the plastic part you look through is cracked and dirty on the other side.

Is there and easy way to clean behind there....or replace the clear plastic piece w/o replacing the whole cluster?

I think they do sell then seperatly. The problem is you have to remove the Dash cover (Top) to gain access to the speedo assembly.

It is really not that hard to get to it just takes a little time and a few Beers to calm down.
