Wide 5 hub and drum help

I want to mate these wide5 front hubs to the buick drum and use them on that squareback spindle. I might a '36 front hub, can anybody verify the year? It is a 2pc hub/drum and i have removed the drum.
What backing plate will work and do i have to cut the center out and create a pocket so it is deeper?
If i don't have the right pieces for to make the combo work can anybody spec the right stuff?
Thanks, oj

 

I think thats a 39 hub. All the other ones I've had were one piece. I was told 36 and 37 had the ribs on the drum and i have ones on my roadster off a 38 which are smooth but are one piece.

I would think a 53-56 f250 rear backing plate would work with that or the 59-60 buick backing plate, but I'm not sure about anything else.
