I have two questions.
1. Does anyone know of a website or store where i can buy an entire gt takeoff kit? (front and rear fascias and sideskirts)
2. Does anyone know where to find clear turn signals?

 

Several companies remove the GT equipment prior to installing their own packages:

Saleen & Roush both resell the factory components. Also NinoSport has a package and components as you requested.
http://www.ninosport.com/GT-Exterior...-07-Mustang-V6

You can buy parts "ala cart" at:
http://www.calmuscleparts.com/store/...ARTS-C248.aspx

I would ask some of the supporting vendors here on TMS before you commit to a package as you may get a deal buying from a supporting vendor.

As for clears, look in the search for clear marker lights, tons of guys on here have them and I'm sure a supporting vendor will supply them.

 

newtakeoffs.com for the body parts
check ebay for the clear lenses

 

Check with grabberpony.com they have takeoffs.

 

thanks everyone. this is all a great help.
