Length of cat: Varies. Stock is one size, by with a 1992 you might have an aftermarket, which would be different. This is a question we cannot even begin to answer unless you get under the Amigo and tell us your system is bone-stock. And if you're under there to see....you might as well measure it.
Do you have stock exhaust? If so, you have all the room in the world down there--it's about 20 feet long with two 90 degree bends. Don't worry about the relacement cat length. Look under your Amigo, you'll understand.
If you have a stock exhaust--don't waste money on a low-flow catalytic converter. Replace the spagetti under there with a pipe that goes straight from the engine and out the back without two 90 degree bends. Then put in a new cat and exhaust while you're at it. Replacing just one middle component in that stock exhaust won't do much of anything.
Hit that search button above. Some rather infamous members tried several different sized pipes to see what gave the best flow. Going to the widest diameter isn't always best--you can get increased turbulance that will actually increase pressure. Search and you'll find it.
Remember that too little backflow can burn your valves and throw off your computer. (even in a 1992! I've had that 1993 computer apart.)
And don't be afraid to take a ruler to the underbody. If you put a string around your pipe you have the circumfrence. Measure the length of the string. A quick calculation gets you the diameter.
