will any Valeon alternator be ok for mk 2?

Will any Valeon (2 bolt connection) alternator from any saxo vtr/vts be ok for my 2000 mk 2 vtr with 2 bolt connections? Assuming the pulleys are the same type, is there anything that differs between, some people on ebay advertise the fact that it's a particular year or mk, or " fits 96 to 2000. My workshop manual covers 96 to 2001. I'm confused about when the changes occurred, either 2000 or 2001, mine i think is a mark 2 with all in one teardrop shaped headlight and indicator, w reg 2000. Sorry to rephrase the same question. Thanks . iain
