1970, 5 lug Brake drum original thickness and minumum thickness
(1/1)
HDAshmore:
Good evening,
I received these drums in another lot of parts I bought and I was wondering if I there were worth cleaning and turning to use. Can anyone tell me the factory thickness of 1970, 5 lug brake drums. Two are 11 5/8" and the other two are 12.5" drums. What is factory thickness and what can they be safely turned to before the are unserviceable. Does anyone have PDFs of the service book pages showing the information?
Thanks in advance for any assistance

Take them to a brake shop and let them tell you. Explain the use, a 70 Mustang. That gets the shop people on your side. If they do the measurement right, it is made from the inside surface to the opposite side.
