My A/C shop emphatically told me to throw the Harrison away and get a new replica or Sanden...but they did test it with nitrogen for free. When tested, i could hear the gas pissing out of the seals straight away, that's when i chucked it.

Also, my A/C shop told me that the condensers in the old Holden's are bullet proof and not to worry too much about them. So far they have been correct!
