Sierra 3500 Denali 6.6L Diesel

  • Automatic transmission
  • 57,000 miles

They wanted me to pay to try a second attempt to repair the leak, It's a part that has no moving parts and is fixed to the roof. I think I can go in any junk yard in the area and find an old VW and the antenna would not be leaking.
