This past week I've been replacing the head gaskets as well as other gaskets along the way in my 05 GTP. When putting the valve covers back on I noticed the front one had a crack in it. I've been calling around to all the salvage yards in my area and nobody has one for my car. My question is whether the covers to the GTP are unique, or will any 3800 covers work? If that's the case, then I think it would make finding one much easier. Thanks for the help.
