Which parts are you missing Jack? I seem to remember you bought an aircon radiator off me many years ago?

As for whether the Q4 aircon is the same as the TS, can't say for sure, but given that Alfa like re-using parts between models and ranges, I'd safe it was safe to say that most parts would be the same.

Is there an eper still active online? You should be able to compare part numbers between the Q4/TS
