I was wondering if anybody knows where I can buy individual parts for a Hirschmann antenna. I'm looking for the small parts at the base of the mast, in particular, and also the exterior chrome nut that surrounds the mast and covers the antenna hole. The antenna I had was a brand-new replacement for the original on my '84 300D, and I hate to have to replace the whole thing just because I lost a few little parts.

Thanks in advance,
Mike
