For you you will need the following.
Fender x 2
Header panel
fender flares x 2
Bumper end caps x2
Bumper
Bumper brackets x2
Headlight bezels x2
park lamp x2
marker lamp x2
grill
In addition you will need to other find used or dealer source the antenna assembly, its different, but will plug into the MJ antenna line.
the hood does not need to be changed, nor does any of the body, there is a bracket which attaches the fender to the headlight bucket, but it is not necessary, and can be bought cheaply at the dealer.
do you also need the newer fender brackets? towards the front where they mount to the header pannel?
You don't have to have it, the header mounts to the fender in two places, its about as necessary on the 97+ as it is on the 96-.
