Muffler Bolt Hole Stripped - Helicoil Saves the Day

Success! Thank you to all who gave me the knowledge and courage to drill out and tap a new hole for a helicoil insert. My first attempt resulted in a broken bolt. To make a long story short, the hole either wasn't deep enough or there was a piece from the old bolt blocking the bolt blocking it and resulting in a snapped bolt end after I tried to tighten it back in. Fortunately there was enough of the broken bolt sticking out that I was able to coax it out with a pair of vice grips. Then I re-drilled - a bit deeper this time. And yes there was something blocking the way - old piece of broken bolt I suspect. Reinstalled a new helicoil and installed the muffler back on - nice and snug and perfect. With a new gasket now. Once again, thanks to fellow fixer-uppers on SBF for their words of advice. And cheers to Donyboy73 on Youtube for his excellent videos on the subject.

been fortunate so far about this problem, Have had several bolts just come out due to the nut practically welded on due to rust .
