Everyone's favorite. I've had one or more on all 3 B/D bodies. Two months ago I got a nice 'new' '96 FWB to replace FTSS, and sure enough my wife comes in last week saying, "I found this bolt where you park your car." RRRRRRRR!!!!!!! It would have been 500x easier to change them all out with GR8 as soon as I bought it, but NNnnoooo I wait til one breaks. All I want to know is how everything's fine for 20 years and it breaks the minute I get it.
Anyway, a nice day spent on some good carwork therapy.
Yep, it was the drivers rear. It could have been a worse one for access. And it could have been an easier one too.
Of course I felt the stud "almost" start backing out and the extractor snapped off flush. I didn't want to spend 3 hours trying to drill it out, so what to do now. I figured I'd try something different.
1. Drill out and clearance for the inboard hole. 31/64"
2. Clearance the spacer.
3. Dig out a socket head bolt I had clearanced 10 years ago for some tight headers on my Monte SS.
4. Drill out the gasket to match.
Everything went back together slick as snot from that point. Well except where I had all 6 bolts tightened and then realized I forgot the gasket to the cat pipe.....
Why post on such a dreaded and boring topic you say? Well, I don't have a welder which is a popular fix. I don't like the idea of the "let's not use that hole and just put 2 gaskets on and crank down hard" fix. And, I'm not buying headers yet
which permits bypassing that outboard hole altogether. It's just for future searchers for an approach I've never heard used before now. and the freebie was I ripped out the AIR Pump while everything was apart.
And I discovered this on the passenger rear. I'm confused what the hell is going on exactly. It could be a bottomed out "too-long" bolt with the head snapped off. I picked up stud extractors to replace whatever it is.
Well, mystery solved. I've done a total 5 broke bolts, but the pic above shows the first time I've ever seen one snap at the head.

And an access hole drilled in the inner fender, -- and it comes out too easy:
