Rear brake drum size
I'm trying to figure out what size brake drums or on my truck. If I measured them what criteria would I use to determin size OD, ID or otherwise. I haven't actually pulled the wheels yet but looking up the parts for my year model and engine size show both 9 inch and 10 inch drums. ??? I really don't know at this point which rear end was factory. Whether it is 7.5 or 8.8, etc.
What I do know is it is a 1994 Ranger Splash Regular Cab, Flare Side with a 2.3L and manual 5 speed. The original tire size is 235/60R15 if that makes any difference. I don't know. I would assume since it is not a V6 that it would be 9 inch drums but why would both sizes be listed for the 2.3L? Anyway any input would be appreciated.
