'86 muffler fix?

[Steve Arbaugh]

Got another question for y’all: my ’86 5ktqa just decided it’s had enough of
the rear muffler, and the thing has totally broken away from the input pipe
and is just hanging there pretending. It makes a lovely rattle every time a
door closes or you brush against the car. Anyhow, if I were to order a new
one, how is it installed? Everything is welded, and being a non-welder, is
this do-able in the driveway? If so, how?

Looking to save a few $$$’s..
