The unit is the real Mccoy - it's not an aftermarket unit. The compressor is a "Nippondenso". Sorry I've been so long getting back to you - haven't checked this site for some time as I haven't been playing with my cars lately although I now have some time & will put a little bit into my GZE into Datto 1200 ute project. If you're still interested in a/c send me an email with a contact address & I'll advise you of my contact phone #.
