hello. i looked for an older audio radio in ebay and found it:http://cgi.ebay.de/…egoryZ14259QQsssPageNameZWDVQQrdZ1QQcmdZViewIt’s now the question: does this fit without major problems in my 80s, since it’s the wider version that was also included in audio 100 c4/a6 c4? what do I have to change to make it fit? gitbs this radio also in the “normal” size? which radio was installed from work in the 80s? unfortunately when buying the original radio didn’t get me there . mfg
