My rear brakes are shot so I figured as long as I'm taking everything apart I might as well do all new. My question is, how do I know if I have 9" or 10" drums? I'm at work right now so I can't just go measure them. I have an 01 Edge 4.0 4x4 if that helps.

 

you have a 10" rear drum....all 8.8's have the 10" drum except for a few of the first 8.8's....

 

Thats what I figured but I wanted to make sure before I dropped the cash on a new set.
