brake drums

[frank long island]

I m looking to change my 6 cyl ranchero to 5 lug by drilling rear axle to 5 stud it has 2 1/2 inch brakes and the inner measurement is 9 inchs all drums I see are listed as 10 inchs is this the total width from outside edge too edge or inner also anyone know where I should look or am I going to have to change the backing plates. found that the aerostar has 9 inch as well as the mazda pickup although they run 1 3/4 shoes so I answered my own ? 's thanks
