Sorry for the delay in getting back to you.
You can just replace the muffler, even if it is a welded system. If it is a welded system you can just cut the pipe off about 2 - 4 inches from the muffler. And buy a the muffler and a couple clamp, you may also need a reducer or 2.
You can fix the hole as long as you can get to it to do a good repair job. Which means you may need to drop the exhaust. If the muffler tape only worked for a short time then the hole is too big and you will be better off replacing muffler. Like I said the repair kit is for small holes.
Not sure about the 88 fitting. Take a look at it and measure it in several places and if all looks good you may be able to use it.
