I posted on the DIY section but thought I might as well post here too.
I am trying to I.D. these rotors so as to be able to get correct parts.
There is a guy on moparts that provides a spacer to use the regular one piece rotors on the two piece spindle. Folks at the dry dock say this is questionable for saftey. What opinions do you all have on such a swap? FYI I have recieved some answers on this and the opinion is 69-72. So this one becomes a matter of shared info, instead of an inquiry. Thanx for looking folks.
The difference between the 69/72 and the 73 is the diameter of the spindle. Measure the spindle diameter.
From the Rockauto site:
1972 and earlier Inner bearing ID=1.25", OD = 2.32"; outer bearing ID = 0.75", OD = 1.78"
1973 Inner bearing ID=1.377", OD = 2.36"; outer bearing ID = 0.865", OD = 1.811"
Also, Rockauto has Raybestos 1972 and earlier rotors for $112 each.

 

hi what was the part no of the 72 and earlier ?
