Looks like they may be some parts we 2003 guys could "upgrade" to that come standard on the 2004. 5
Air cleaner box "heat blocker"
Hood insulation
Valve cover hold down bolt isolaters (need to see those)
Some of the 4" exhaust parts maybe?
I'm sure there are others but it would be nice to be able to add some of the "impoved" parts where feasable
