5.9 Magnum flywheel - DIY with bolt-on weight??
Just a thought, maybe I missed it, but you are adding the weight opposite where the holes were in the other flywheel, right? I could see that messing someone up, "factory modified the flywheel "here", so that is where I put the weight". Adding weight would be opposite of where you would remove weight.
I'm sure you thought of that, just making sure.
