My alternator is on its way out-How do I determine which one to order

How do I know if I have the 150 amp or 180 amp? I have the water cooled early alternator, but don't know how to determine which one I need to order to have my mechanic install.
Do I decode by vin, or options?

Thanks

Not sure which one you have but I bought a brand new (not rebuilt) Valeo for about $200 online recently. It is air cooled though.
