You don't repair a muffler, you REPLACE it.
If there is a rotted hole in the muffler please replace the muffler. However, if there is a small hole at the bottom end of the muffler it is there to allow water to escape.
Muffler bearing do not exist.
In the fuel tank.
There is a circuit breaker thaich could be bad.

If you are replacing the brake lines ( metal ) then just use your better judgment. They do not have to follow the original route.
Call your local wrecking yard as they have crossover books.
