Bob-
You will have better luck with this if you remove the trans crossmember, and gently lower the whole thing on a jack.
I guess I won't recommend you do this if you have wiring harness problems- the flexing might be fatal to the existing crusty harness.
But as long as the wiring is ok, you can lower the drivetrain quite a bit and access those pipes. A flare nut wrench would be best, but I don't remember offhand what size it is.
If you find there's no other way to get to it, I'd take the exhaust apart at the 3-bolt flange for the headpipe. Don't mess with the cat. Just get a new flange gasket ($3 or so) and 3 M10 copper exhaust nuts (dealer or much cheaper at FCP Groton). You can reuse old nuts but only if they're in fine shape.
The exhaust is a bit heavy so you'll want a helper lowering and reinstalling it if you're not strong. You end up having to hold it up while you install a nut, using about 16" of extensions. The nut size is 16mm BTW- make sure you have this socket before even trying. Many sets don't include it.
Good luck!
