Don't know if you all have seen this on any other forums, but Mad4WD is running a helluva deal on their RockCrusher diff guards. They are full replacement covers and they are heavy and strong. I've seen them before and now you can get a D30 covers shipped to you for $60.
I've ordered 2 new ones for myself since my old face mask style guards are pretty worked over. From what I understand and from what the site says there could be a 45 to 60 day wait for delivery. They will however not charge your card until the product ships. I guess the boys in AZ have been buying the hell out of these the last few days after it was posted on our board and the owner of Mad got on the board and said they are in the process of casting the covers and have a couple runs going.
They are worth the wait. I'm paying $110 for a D30 and D44 cover shipped to me. That's better than 1 full cover will run you from anyone else and also cheaper than just one of them after this special is over.
