Which Alternator do I have?

Hi All,



So the Alternator Pulley is dead. Reverse clutch bearing - loud rattle noise in gear when its cold. Goes away when its warmed up



I've been sourcing a replacement pulley for it, put in the Vin and it comes up with 2 types of alternators



One is a 110a and the other is a 140/150a



How am I to know which one I've got without having to pull out the alternator to get the part number



Any help is appreciated
