I have seen a few of them, both yellow and orange (my fav) but I have no idea how many were made.

The 5.4L V-8 and drivetrain is the same as in all other 2WD 5.4L F150s . . . 260 HP @ 4500, 350 Lbs-ft @ 2500

check the door decal for the trans and axle code;

TR: E is for 4R100

Axle: 19 is for 3.55 non-limited slip
17 - 3.31 non-limited slip
H9 - 3.55 limited slip
H7 - 3.31 limited slip
H6 - 3.73 limited slip
