there sure is a diff. what all pices did the conversion need?
and how much do u think it would cost??
not to sure on the 04 body style i know with the like 97 body style you could swap them cause the junk yard gave me a set they said were 2x4 but they were actually 4x4 cause it sat alot taller
"go to a junk yard and get 4x4 coils they taller than the 2x4 i dont know buy how much but i know they are or maybe a combo of both"
What else is involved w that?
