Heater Box Mounting (with J-Hook)

All thread rod.

This is 73 so is probably a little different, but the idea is the same.

First pic is where I sealed up the hole in the box from the tab for the J hangar being ripped out.

Second pic is after it was all fixed with the J hanger bracket JB welded back to the inside of the box.

Third pic shows a barely noticable line where the new faceplate I made to cover the repaired surface is.
You know that stuff that looks like carboard in construction, but is made of plastic?
(they make advertizing signs out of that stuff)
That's what the paceplate is that covers the repaired surface. (painted black)
