rear brake swap question

I just acquired a nice set of 11x2" brakes. Not sure what their off of other than some other Mopar. My plan is to replace the small 10x1-3/4 brakes on the back now with them and hopefully have better holding rear brakes cause the stock ones suck. Question is has anybody done this and if so what brake drums did you use? My axles are stock but Moser re-drilled them to the large pattern and installed 1/2" studs so the drum would need to be large pattern.
