From my experience, you're gonna have to cut off some of the metal on the chassis to get 1gb rear and front end. Talon bumpers are way different than eclipse / lasers ( rear end). The only tip is to be careful, use the proper tooling and be sure to not fail at metal working
Just realized you're only doing front end. I'm 90% sure you're gonna have to cut a bit still. The 1ga pop up enclosure won't allow the 1gb headlights to fit properly. There's some wiring changes too obviously.
