As we know these drums were factory made by Chrysler in one piece riveted with hub (?) and possibly machined that way 57-59 and probably back to 30’s . . So perfect centering .

As I still have no success on finding 11 x2 Dodge rears ,( 2.5 are out there ) — and someone had very poorly modified mine by removing original drum , adding another loose drum ( later mopar ,? and new studs ) They used the stud holes to locate , totally inadequate , — as done.. Runs out .060 + and cut .100 over ( dumb..)! But all that driven by lack of availability ?
So in looking , there are new 60-61 11 x 2 drums around for 60-61 Dodge . They are loose without taper hub .But as (I think !) I recall 60 dodge used tapered axles like our 300 do up till 62 . And these new 60 drums fit on front , too (!)
So are 60 mopar drums serviced separately from the hub ( why different drums listed in 60-61 vs 59 back? ) Dodge 11x2 59 back with hub drums are impossible to get , we may face this on our 12” drums very soon . Still available ( Kantor last year ) but waning supply and very large $
.
Does anyone know about this ? The 60 dodge drum has a defined toleranced pilot hole , I assume for centering , but the 58 hub I have does not have that machining , 1960 must — although I think I can add that ? Maybe 60 hubs all have it , Or possibly same guy cut the hub face to align new drum he used in and out?

A drum revision in 60 ? Also in the 60 dodge front and back drums interchange — a very rational reason to allow hub and drum to separate ?? although the 60 hub has rivet holes too

Obviously all probably applicable to 300 too , just larger drum ... ??
comments ?
Thank you ,
John
