Where can I buy a fuse box for my toyota land crusier 1994

Since I have no idea where on this blue ball you are I can't give exact locations, but the bottom line is this, the only way to get the part is to buy a used one, new will not be available anymore due to the age of the vehicle. Many online sites will help you locate a salvage yard that has your part, they are used part locator services, I have used them any times and they work well for finding used parts. I have attached a few links for the locators I found in a quick search on Google. Good luck.
