12 Bolt Posi swap! "Blue Collar" The 66 Impala gets a Yukon Dura Grip!!

The long awaited posi rear end finally gets completed just in time for Sick Summer. Blue Collar has needed this for a number of years, and we finally took the time to swap out the 2.73 open rear diff for a nice Yukon Dura Grip with 355 gears! Now, lets see if it survives the test of Sick Summer! #posi #burnout #sicksummer #draganddrive #theholubproject #THP
