Help get brakes on my model A.

Im putting '46 ford juice brakes on my stock model A. Ive used the search function to no end and can not find my answer, ive read it on here before but cant remember or find the thread. Im useing new drums that i bought from MACs and i cant remember if im to machine the drums or the backing plates and how much. I seem to remember it was the inner lip of the drum but on the MAC drums it looks as if it comes this way. i guess i could go trail and error but the drums werent cheap and i'd like to do any machining before i mate the hubs and drums. thanks

 

Search in the tech section next time.
