Thanks Frank, very wise advice. Not sure which way to go as it is not urgent, although I do know I would rather keep the car original than make changes the next custodian will not appreciate.
Any advice or recommendations on this topic is most welcome.

A lot of the cars, especially in warmer countries had ac units fitted from the dealerships for exactly the reasons you are mentioning. I don’t think a prober installed AC system would lower the value of the car. Why are you worried about the „next custodian“ if that’s something you like?

Thanks Dirk, great advice, agreed and I may go down that path…. although before I do, I am exploring all options before installing a third party unit.
I was also going to upgrade the Becker radio and then found with modern technology you can pair a quality portable Bluetooth speaker to your phone and voila, amazing unlimited music with no additional changes to the originality of the car.
Sooooo I was hoping their may be an aftermarket portable unit that does the job without changing the cars structure. I await further responses.  Failing this, I proceed as you described.
