Pic #1, This was the 3rd attempt, and the one I got to stick. I had to grind off a little of the weld on the outside of the nut to get the socket on.
Pic #2, SUCCESS!!! Since these bolts are "glued in" (prolly Loc-tite) from the factory... the heat from the weld loosened it up, and it came out EZPZ!
Pic #3, The hole with no busted bolt in it!
No need to show putting things back together with new bolts and gaskets. If you got this far... I'm sure you can get it all back together.
Hope this helps anybody that has to do this fix. It's a PITA, but doable. Bottom line is... use a welder on the first attempt. You WILL break off an easy out in the broken bolt, since they are glued in from the factory.
Good luck!
