Ok what you have is a budget aftermarket setup. It's Still ok but (trails off into the distance.....)
The bracket is homemade and has no tensioner pulley from what i can see. I like the genuine stuff but it's getting harder to find. The best part to get for these setups is the original heater box with evaporator, once you have that everything can be adapted like the lines, condenser and later model compressor. I would strongly recommend getting onto Gordon and asking if he can pull the bits out for you. There's jay in Ballarat who has the same gear but he's prices are full on retail. If you get stuck let me know and i'll go wave some cash in front of Jay's nose and get him to bite.
