Question about ordering '07GT

Personally, I'd purchase outside of a dealer, they will overcharge. Not to mention their hourly rates in labor.

I'd order online, numerous places cutting deals on all the parts you asked about. Then find a reputable installer in your area or do it yourself to save even more. The parts you want to replace are an afternoons worth of work. If your not the type to do this work, then do like I said find someone reputable, they won't charge like the dealer will.

I got the dealer to give me the FRPP parts at cost for buying the car from them. I think it was around $960, not sure if you can find a better deal elsewhere, probably. And that's not installed, I wanted to do the install myself .
