A couple jargon questions
 

I have noticed some people saying they have a screw when talking of their engine what is this. Also, with the overhead console some people were saying they have a rail instead. What is that.

Haha had me on this to until I thought about it. I believe it means Super Crew.

SCREW= super crew, SCAB = super cab

Some of the FX4 models have an overhead modular rail system that lets you add and move overhead bins inside the cab

They are references to the cab style

screw - super crew
scab - super cab

The overhead rail is a modular design for storage and such. My brother has it in his King Ranch and the storage modules are movable on the rail and he can order various additional storage options to place on the rail system. Someone else will have to chime in as to which other trim levels can get the rail system. It was not available on my FX4.

i have it on my 05 fx4 scab

but i cant find where to get more bins

Awesome thanks for the info. I love my new screw ecoboost. If I have any more ?'s I will post them here thanks a lot.
