Which alternator??

Hi Guys, Update on the freelander project MOT, Fail!!! all the work I have done was fine but the brakes just were not up to scratch and the alternator vacuum pump is to blame I have been looking for a new one but there seems to be conflicting info, some suppliers say 90 amp and some say 105amp, Can anyone confirm which one?? It is the 1999 L-series 2.0 Di, Manual with aircon.

Cheers!

If it has aircon I'dguess 105 amp one. Won't hurt either way as long as it fits the same.
