Ready to throw down for a locker.

I’m over my little truck being tame and cute. I’ll spare yall my history but I’ve gone around the mountain a couple of times scratching for a traction upgrade. I do a little driving in the Chihuahuan Desert – nuff said?
I’m ready to go with a mechanical locker but I doubt that one is available for my CA39 axle (29 spline, 3.90/1 gear, C200) So here’s my question; what axle do I need to get for proper track width, with a single ABS sensor on the yoke, that will accept a mechanical locker. I’m not talking ABS here (been there, got burned) – just a straight mechanical locker.
