Can someone tell me what type of rear axle comes in an H3? How about the WMS-WMS measurement (wheel mounting surface - wheel mounting surface).

Thanks

 

I am pretty sure that the H3 rear axle is cast iron and manufactured by American Axle & Manufacturing. The front axle is AAM's Powerlite aluminum axle. The wheel base is 111.9 but not sure what the inside rim to rim measurement is on the axle.
