I have a 2wd 1999 Ranger. I went to the dealership to order new drums. He asked do I have the 9" or the 10 ". I said I don't know. He gave me a measuring tape to go measure. I measured 10" at the backing plate (the only part I could get to in the parking lot)
I told him the backing plate measured 10" but I could not actually measure the drum. He said if the backing plate is 10" then the drum is 10". So I ordered the 10".
After I got home I pulled the wheel off and the drums are 9" ID on the drums.
So unless I can stop the order I am the proud owner of $300 worth of 10" brake drums and shoes.
Question: Is it possible to convert it from 9" to 10"?
