Searched all over the damn internet and couldn't find anything, even called the local parts guy and he couldn't tell me so maybe someone here will know.

Looking for the rotor diameter for an 8 lug 3/4 ton mid 70's chevy dana 44. From experience I am guessing that it is 12.5" but I need to know for sure. Thanks in advance.

12.5" diameter with a 2.125" offset.

That's what i was thinking. thank you kindly
