Tinting Rear Window

[ltwnfdc14]

I went to order some of that pre cut window tint for my truck on order and the dealer said ford is making two different solid rear windows. One the clear part of the glass measure 15" and the other 18". The only think I could think of was maybe a crew cab has a smaller back window?? Anyways I dont have the truck yet so any info would be great. I guess Ill have to go to the dealer to do some measuring.

not sure of the rear window (Slider, Mine has 3 pieces)
Lumar film == best $$ can buy (imho)
and when your putting the film on front/leading edge of front doors was the hardest part
to get laid down. The front door speakers are so close to the glass it was a b?tch getting it in their. otherwise the film installation was a breeze. Good luck
