Universal Traction Bars install on a Duster....

In pic number 5 of the cal track wheele bars, that mount on the axle does not wrap around the tube?

I can say from experience that is a great way to destroy a axle housing.

I can post pics of a housing torn to bits by that same type af attachment. The one I destroyed was done with a big slick and maybe 300HP. It literally tore the axle tube, let the pinion swing up, sheared the pinion off and let the drive shaft into my personnel space. (I was very lucky to not get hurt)

I would get some tube that fits over the housing, cut it in half and fully weld it to the housing. Then weld your mounts to that.
