I penciled a line with a 12 inch square perpendicular to the body rear panel then  used a air cut off tool to cut 1/4 inch below the line.
	By placing two pieces of flat stock a home made brake can be made. The final fold can be done by using a crescent wrench to bend the metal.  I did this to keep the strength on the quarter panel.
I used a pop rivet tool to re mount the fender back to the body. The tool & plastic pop rivet can be bought at any large hardware store.
By using a STANLEY® utility knife a clean cut can be made.
	Final result is much better
