Items in in Blue is optional. you can reuse most of the old parts including the item #10 the Bumper Beam. Items 18 and 21 I would recommend for it to be replace.

For items 17 and 18 you can reuse the old sockets from the front indicators on the 91-01 bumper. Also need to extend the park and indicator wires to reach the 02 headlights.
Aftermarket HID kit instead of the OEM HID to cut cost. There is a hole for the OEM Control unit on the bottom of the headlight that needs to be covered if an aftermarket HID is used.
I bought headlight brackets from Dali, SOS and Downforce. The Downforce brackets were the best.
