Blaupunkt CR3001 Cassette AM/FM Radio knobs

[ronmanfredi]

I have a 1982 Avanti II with the Blaupunkt CR 3001 Cassette Radio. The control knobs on it were falling off and the insides were just shot. I looked for several days and could not find replacement knobs. This radio has 5mm shafts, instead of the more common 6mm and 3.5mm (Japanese car) ones. I then discovered that GM used a 4.9mm shaft for the rear radio speaker knobs and purchased a pair to modify ($12). The knobs are much deeper and could be used as they were, but I wanted to retain the stock knobs if possible. So I used a Dremel and cut them down until the fit correctly into the Blaupunkt knob and they worked perfectly. The inside of the GM knobs have 4 ears connecting them to the outer ring, so it makes it easy to trim so you can center it into the Blaupunkt knob. Hopefully this will help others!
