Why are 04-05 the odd man out?

[Gorecki]

What's stopping you from getting some 97-03 arms? They're identical other than the 97-03 arms having a place to bolt sway bar end links to. I'm going to do this so I can do a larger sway bar on the front.

Hey, you've got a really good point!!

Please do share the results of this as the only point of reference to the differences I have are sketch drawings and part numbers. According to the part numbers below, the *only* difference is the control arm itself. The bushings and ball joint are exactly the same!
