Neep help with Rear Drums A.S.A.P Please

Are they small bolt pattern or large?

I just read this on another site:

"All Mopar rear drum brakes interchange to all axle housings, so long as these rules are followed: (1) small bolt pattern drums go on small bolt pattern axles (i.e. 10x1.75" drums can only be used with 5x4" bolt pattern axles), (2) large bolt pattern drums go on large bolt pattern axles, (i.e. any 10" or 11" drum that came on a 5x4.5" bolt pattern axle can be used with a 5x4.5" bolt pattern axle), (3) brake assemblies are swapped as full assemblies (this means a 10x1.75" drum is used with a 10x1.75" brake backing plate, and 10x2.5" drum is used with a 10x2.5" brake backing plate).

Does this help?
