Front Drum Brake question?

I have a nice set of 16" 49 Ford wheels with 5 x 4 1/2 bolt pattern and want to use 37 to 41 spindles on a 36 front axle. Can I use some 60's Mustang baking plates and drums or do they make a 5 x 4 1/2 bolt drumk for the 40 backing plates I have?

 

just redrill you juice brake drums to 5on4-1/2

 

they made adapters for big ford to little ford too.i have some...but there on my car.not sure how easy they are to find.

 

i think Mr gasket still makes em, the real hard ones to find are just the opposite!
