Hello All,I was hoping some one out there could help me with a small problem I have. I am in the process of performing a 4" to 8" sync 3 upgrade on my 2015 Expedition XLT and I am in need of the mounting brackets. The Sync2 or Sync3 brackets will work as they are the same. Does anyone have a set they are willing to sell? It seems that the 2015+ Expeditions have a unique set of brackets that are hard to come by on their own. If anyone has a local pick+pull yard by them I would be willing to pay for you time if you could help also...Any help would be greatly appreciated..Thanks,Dave
