Is the rear offset also? And how wide do you want to go? Your stock CJ6 axles are around 50.5" wms and the J10 are going to around 64" or 65" IIRC.
Also curious about the automatic hubs. Are you saying they automatically lock and unlock? I've never heard of that on these axles, but they did come with drive flanges on full time 4x4 models (front hubs don't unlock).
They're pretty good axles if you want to go that wide, especially if you've got a D18 t-case with rear offset. If you don't want to go that wide, look for '79 and back wagoneer axles. They're about 5 inches narrower, but otherwise the same.
