need help finding replacement air-con servo unit

[bratwurst_boy]

hey guys, i've just had my air-con looked at and fixed, but the air-con mechanic says that my servo unit (controls the mixture of hot and cold air) is busted, so i was wondering if maybe an older galant unit (must be climate control) would fit or maybe where to get one from NZ as i doubt mitsubishi australia would have them.

cheers
