The 'post valve' car radios generally have a connection for operating the electrical motor on the antenna...as said klimacher. The post is very old of course...I own a Carlsson (white with original red stripes) and an Anniversary. Nice carsIn chasing info on how many 2.3 Carlssons were made the best available world-wide figure was 329 cars.There were far more 2.0 Litre models. I also have a Cosworth 4x4 Sapphire stored in France...I prefer rear wheel drive vehicles but have owned my SAABs for some 20 years...I flew to Victoria to pick up my Carlsson. I had suspension done by the best there is...Heasmans (Steering and Suspnsion) at Sydenham. I have been a customer there for 58 years. They also replaced all engine mounts..and I then drove it to Queensland. My pristine Anniversary came from Eastern Suburbs. Its turbo was crook. I replaced it and drove it to Qld...great car to drive and abit differnt from the Carlsson. As with the 7 series BMW, SAAB 9000 Carlsson being just somewhat better, the 9000 2.3's are the best drivers car of all.
