will these drums work on a bodies?

ok,heres another idea i had.Well,more like i remeber reading somewere that if you swap the backing plates from a front drum equipped b body,the 10 inch x2 inch front drums will swap right over.I happen to have a 71 satellite sitting here,with new front drums on it.I might try that swap tomarrow and see what happens.It it does work,people will just about give you these drums,because they wont disc brakes.As long as you get the backing plates with,the rest can be bought new,like shoes,spring kit,etc.I believe the wheel cylinders are the same also.I looked up the part #s for bearings,and they are the same as for the stock 71 dart.again,these drums call for a different oil seal,so im sure there is something up with that
