You're doing exactly what I did. Ah the memories. Anyrate, I just got done with my trunk and frame rails too and I used the Goodmark extensions. They seemed to fit good after some tweaking. I would use AMDs for a heavier gauge metal and I'm sure the fit would be better too. I don't know if they are out yet or not. But the Goodmark ones are actually OK. Stay away from their wheel housings though. Check my site #2 and you'll see why. Hope that helps!

Cheers
