The 12" drums you are looking for  are front L/R drums with rivited on hubs.

You have a 8 passenger long wheel base Dodge.

It uses the heavy large Dodge ,DeSoto and Chrysler LWB, heavy chassis suspension parts.

Same as any 1949-50 Chrysler New Yorker 8 cylinder sedan, cpe, wagon or 8 pass sedan 131" WB car...

Std 12" Chrysler Royal, Windsor, DeSoto drums use a small drum hub with a 4-1/2" wheel bolt pattern. 

The heavy chassis LWB 12" drums are large hub with a 5" wheel bolt pattern and large hub 4" hole.

That's what you need.

Ask the person showing the separated hub and drum for the drum hole diameter...it will most likely be just under 3".

Don't buy just a drum...way too much trouble keeping drums true and properly and accurately mounted.

If you were close I would sell you the needed drums but way too expensive to to pack, ship those heavy drums from Western Washington.

What seems to be the problem? Aren't the rivet holes precisely drilled to center the hub? 🤨
