Okay, let's see how you guys do with esoterica! The little toothed drive belt in my Hirschmann electric antenna is stripped. This is the 65_0876 antenna for all y'all who have the BMW parts catalogue CD. It's a shame to toss the whole unit; anyone know where I can get a replacement belt? The belt is about 1-1/2" (38mm) dia x 6mm wide.
