Rear End ID Help

Trying to figure out aproximate year or year range & type of vehicle this came out of.
Need to get backing plates & brakes.
Looks to be small bearing & 5 on 4-1/2



any help would be appreciated.

 

I believe that is the highly prized 'round back' 9" from 1957/'58. if it has 5 x 4.5, it should be from a Ford p***enger car of that era.

 

Looks like the good one. They came in small and large bearing sizes. The orignal brakes are narrow...kind of hard to find parts for them.
