Dana 30 lockable hubs
 

Here is my question for everyone. Is there any way besides buying the warn kit to get lockable hubs on my Dana 30 high pinion? The axle is from a 93 wrangler. I don't want to switch to a Dana 44 or do another axle swap. My question is, is it possible to find either an axle that has lockable hubs on a 5 X 4.5 lug spacing and the knuckles will bolt up to the Dana 30. Or another possiblity would be to change out the entire knuckle off of the tube out.....
