Dude, seriously. We gave you our best advice in these threads from 2021 - 25 August 2021 https://aus300zx.com/index.php?threads/1991-300zx-twin-turbo-a-c-compressor.338927/ 29 Sept 2021 https://aus300zx.com/index.php?thre...difference-between-na-and-tt-versions.338957/ Chewy went to the trouble to post the parts diagrams, other members tried to help, and I got myself covered in grease and turps for you but you are no further along with this a year later. Maybe just wind the windows down when it gets hot. Can you manage that?
