Is there differences in front end / grill sheet metal between 2004 and 2005 GMC Sierra's?

I want to order a winter grill cover today from Cabela's (getting cold here in NJ, and my truck did not come with these winter covers)

Cabela's website shows for years 2003-2004 but not for 2005

Same thing. The 03 and 04 covers will work on an 05. This is not the case for Chevys however.

Thanks very much!!
