Yeah, I have always love the FX4L2 trucks, both visually and functionally, and I have done almost everything I can to get my truck to L2 spec.
The defining features of the FX4 Level 2, as I can remember them, are as follows:
4.0 SOHC, manual t-case (available but not standard), the special seats, the special shifters, the 31-spline 8.8 with Torsen unit, 4.10 gears, 31" tires, and the Alcoa rims (optional).
I have a 4.0 OHV, and I have a SOHC waiting to be repaired and put in. That is so happening. I have always had a manual t-case. If I could find a set of those seats with red on black I'd jump on them, same with the Alcoa rims. I have an Explorer 8.8 that I installed a Torsen unit in. The chrome shifters won't fit my stuff, but if I found a set I would look very hard into making them work. As it is I will probably get a Hurst shifter for the trans one of these days. The only thing left is the 4.10 gears which I don't want. I have 3.73s and I am quite happy with them.
I think the only change I might make to gearing is to swap transmissions between my Ranger and my BII because the BII has the 29" tires still and a 2.9 M5OD in it with the lower 1,2,3 gears. That BII just has too much zip, I can't keep the speed under control.
Given all that she is about as close to an L2 truck as she will ever be, so I think she needs the decals.
