I'm not sure about the fenders, but I know you'll need the hood, front bumper cover, absorber, and maybe the reinforcement too. For the lights, you'll need the header (headlight mounting panel), and you'll have to hack into your wire harness to change to the correct connectors for the single bulb/dual element set up in the later bodies. If you're changing to a GT front end, it'll look pretty funny if you don't complete the job by adding the correct cladding all around the car too. That means getting both rocker moldings, the GT rear cover, and all of the associated mounting hardware too. I'm with rl though, I like the 4 eyed monsters.
