well, like the title says, i was wondering how would i go about measuring my drums so that when i replace them i know i bought the right size without having to go through the trouble of trial and error... and please, keep the smart *** comments to a minimum

 

You don't have to measure them...just go to Autozone or Pepboys, tell them the make, model, and level of your car.... and they get the right part for you.
