alternator and fan belt

Hi,
I'm looking for a part number for my alternator and fan belts.
I have a 93 Discovery 3.9 V8i and there seems to be a number of variation of belts for the disco 1. there seems to be a cross over from the 3.5 version to 3.9 in this year (and a mix of parts) and I'm not sure belts designed for the 94 on v8i will fit on mine or 89 - 93 3.5 belts would fit on mine. I tried looking for a 93 3.9 belts but couldn't find any.
could anyone help?

Cheers.
Dan.

You may be able to see a number on the belt, if it's a Land Rover part number then it's easy otherwise a make and number would help.
Have a look at Rimmer's site for part numbers. Rimmer Brothers
