Hey, I have an 05 TL, I got in an accident and my front right quarter panel needs replacement, front right headlight (I want to buy custom Jewel LED lights for it), I also need to get a new front bumper, and I would like to put the 07-08 type base bumper for the rear. Any suggestions for me?

 

Throw on a 07/08 bumper, check out car-part.com for that and the front fender.

For headlights, you'll need to find someone who will mod custom jewel eyes for you.
Expect to pay close to 2000 to get it done, plus the cost of a new passenger headlight that you'll need to source (car-part.com is great for that too).
