1971 Duster 340 10" front drum brakes - what other Mopar brake drum hubs will fit?

Yes, my preference is to stay with the BBP, and my driving is between mild amd spirited and definitely not crazy. I haven’t ruled out going back to drums in all 4 corners - but is it possible to redrill Duster SBP 10” front drums/hubs to BBP?
yeah it's possible to go out to 5X4.5 on the 10" hub, there's enough meat. you just need a competent machine shop to do the work.

obviously you'll need to drill the drum as well. down the line if you need to replace a drum, you'll need to buy another small bolt and have it drilled because factory big bolt drums have a larger center register.
