I used the heat and beat method to clearance the frame. It came out okay, but if I had had a different hammer it could have turned out nicer. And here I thought 12 hammers in the shop were enough.
To be sure the box no longer hit the frame I sprayed a quick coat of black paint on the frame (Photo #1) and then put a thin layer of anti-sieze on the box (Photo #2). With a couple of studs to locate the box correctly it was easy to see any place the box touched. In the photo the dimple looks like I used slag hammer to beat it into shape. I was using a flashlight to illuminate the frame for the first photo and some how it made every small divot look like a huge crater. It actually is much smoother in real life
