Duster drum brake size from factory?

That is 99.9 % of what USA equipped "A" Body cars came with from the factory.....
That is standard .... they did have two different sets of front calipers & pads --- what is termed
"slider" pads where the pad slides into the caliper -- or -- "pin type" pads where the brake pad
is held into the caliper with two pins at the top.....
At this moment in time -- I have N.O.S. ++ Asbestos ++ Brake Pads for both -- and N.O.S. ++ Asbestos ++ Rear Shoes......
Still today, the only efficient, quality way to stop a vehicle.............. Yours, Craig .......
