Pretty sure that these are 11 x 2 1/2". Available from many sources but Rockauto seems to be the cheapest.
drums That's what I would have assumed, but when I looked up drums on Rock Auto they didn't show an 11x2.5 drum. Only an 11" drum for the rear with no width.
Now that I checked the 1965 numbers vs a 1969 Coronet, they still only say 11" rear with no width but the part number is the same. I just hate to order something, especially a heavy set of drums, and have to send them back.
I guess a 383 car with 11" drums got a 2.5" shoe for the rear. I know that the fronts on this car were 11x3".
Thanks
