big bolt pattern conversion can you use truck drum brakes

Pulled the trigger on a Dr. Diff axles setup. By the time I shipped my axles to Moser, they cut them down, and I bought bearings, studs, and had them pressed on it wasn't that much of a difference in cost. And, I ordered at 11:35 and just got an email at 2:30 saying it's shipped. I can be cruising by next weekend. Thanks for the quick responses.
