Hi all, snapped the mast on my 1982 300td and am looking for a replacement. The antenna motor is a Hirschmann Auta 6000u - 485. I was having trouble finding a mast that will fit this motor, but think I found it here on PelicanParts. The description says it fits the 600 U 485, I imagine this is supposed to mean "6000" U 485? Want to be sure I get the right part...
