Yup.. it sure would.. they just need to update the numbers.. samething happened to me when I shop online or in some catalog.. all the parts were "fits 99-02" but never 03.. now they are all 99-03.. just give them some time.. people are lazy
any part for an 03 would fit an 04. i have an 03 and my dad just got an 04 mach 1, other then mach 1 stuff thats different everything is an exact fit! what mods you thinkin about doing?
all that stuff will fit on an 04 that is for an 03, and the service department should be cool with all that stuff, none of it should void your warrenty
Don't let the service dept intimidate you...it is, after all, your car. Of course, you don't wanna piss 'em off either.
My wife took her 01 GT in to the local Ford dealership service dept because of a tiny oil leak near the harmonic balancer. At the time, her GT had a C&L MAF, Nitto DRs, D&D LCAs, BBK off-road H into Flows then dumps, etc. They swapped the harmonic balancer without blinking. Of course, they may treat me differently 'cause she's cute and I'm not, so I let her deal with the service manager or service techs all the time!
