I have had the AWE axle backs installed about a month now. The sound is just what I was looking for, I can drop into S to get that muscle car sound, but just driving normally in D it shifts out early and sounds tame. I think it is perfect for the convertible.

Yeah, my last experience with Power Ford put me off too. I don't trust them much past an oil change. They ended up buying me a new wheel when damaging mine just rotating the tires.
I've seen your 69 several times. That's a sweet car. I drive La Orilla daily on my commute to work.
I installed the mount from Proclip earlier this week. It is perfect, using the iPhone 6plus mounting bracket.

Mine is a magnetic GT, 50 year appearance package. I had the Ford Racing cat-back installed, and tint... that's about it. I have seen a ruby red GT, I think the guys works down here too.
