The belt you will need depends on your layout. You most likely removed the Power steering pump, Where you mounted the Alternator and tensioner all changes what belt you will need. If you have the original belt, cut it and wrap it around your belt drive system and take a measurement. You will want to compensate for the tensioner movement, i like to load it fully so I get the minimum length and then go a size or 2 up from what ever that ends up being. Get what you think and the next length up. Can always return the one you don't use. It is a bit of trial and error.
If you used someone's prefabricated alternator relocation kit, they should know what the belt needed is.
