Antenna Base 99-05 VW Passat Beetle Jetta Golf GTI MK4 B5 B5.5 1J0 035 505

For sale is one genuine VW/Audi antenna base, part number 1J0 035 505 B.  Includes antenna base and mounting nut (see photo); does not include antenna.
This item is in used and functional condition.  I purchased it from another parts seller with the intent of replacing the antenna base on my VW, but it turned out that there was nothing wrong with my existing part and thus no longer require this one.
