65 Dart 273 hi-po. Are these 9 or 10 inch drums?

So, you've added QA-1 control arms & KYB shocks but your still running 9" drums??? WTH???

KYB shocks were $25/ea. QA1 was about the same price as rebuilding my factory stuff. 9" drums stop the car without having to replace my wheels before I decide what I want to replace them with.
