this may be a dumb question, but why is it that even though everything is completely different, the lockers are still interchangable between them???

Basically, as I understand it, in our trucks the front diffs are rotating "backwards" when traveling forwards. The gear teeth are stronger when the drive side is taking the load. On our trucks the coast side of the teeth take the load when traveling forward.
On newer trucks, they flipped the diff upside down, so the drive side of the teeth was being loaded when going forward.
From Pirate4x4:
Ring Gear Tooth Nomenclature
A – Top. The top of the gear tooth, a.k.a. Face, Top Land
B – Root. The bottom of the gear tooth, a.k.a. Flank
C – Heel. The outside-diameter-end of the gear tooth
D – Toe. The inside-diameter-end of the gear tooth
E – Coast. The concave side of the gear tooth*
F – Drive. The convex side of the gear tooth*
* Don’t be mislead by the terms “coast” and “drive”, as the ring-gear can be driven by the pinion on either side of the teeth. Which side of the teeth will depend on if the gear-set is standard or reverse spiral and whether the vehicle is going forward or in reverse.

I understand the difference on our axle and newers...
Thanks from Mexicali Mexico....
