Want to replace Coleman A/C shroud...

Mine has seen better days and needs to be replaced. As for exact model I understand I must take the top off to find model number information. My question is where should I go to find a replacement. I'm looking for the classic style, what I have on it now, just want a new one. I have found through my brief search that it might not be available...hmmmm. Also the best price would be helpful...don't have a big budget... Any suggestions? Thanks... Mark
