2 Gearshifts | Twin stick shifting in my Grandpa’s old Mack

1956 Mack LTH with a Cummins Big Cam 3 400hp and a Mack quadruplex twin stick transmission. This is my grandfathers truck and the truck I learned to drive in. I wanted to take you guys along for a ride picking up the Caterpillar 977H to bring her home!
