Well i was going to strip the front of my car down to spray and while taking the driver side wiper arm off the whole braket started coming off from it being rusted and was wondering if anyone had something similar happen or any recommendations to repairing it? pictures

WELD IT UP... MAKE A NEW MOUNTING BRACKET. ON A PIECE PAPER TRACE THE BASE OF YOUR WIPER ASSEMBLY TO MAKE A TEMPLATE (TRACE BASE AND MARK HOLES). I'D USE 1/8" TO 3/16" STEEL PLATE FOR THE MATERIAL, WIRE WHEEL TO CLEAN ALL PAINT AND RUST OFF OF OLD MOUNTING BRACKET DONT GRIND IT AND REMOVE MORE METAL THAT'S NEEDED, YOU WILL USE EXISTING METAL LEFT TO WELD THE NEW MOUNTING TAB TO THE EXISTING PIECE THATS LEFT..WELD A BOLT TO THE UNDERSIDE OF THE NEW PLATE TO REPLACE THE RUSTED OUT ONE. DRILL A COUPLE OF HOLES IN THE PLATE FOR PLUG WELDS
