I should have paid attention to the name Miller. Of course you would want to machine it. LOL okay yeah go for it if you got the machines to do it do it. But I wouldn't pay $65 for a front cover I'd give $30-35 but that would be my top dollar.
Trust me, nothing special about Miller. No e relation to the welders or the beer. I wish LOL!
