Bar Option 3: standard shank and adjustable shank
Place the bar with the canvas flaps over the shank of the tow bar tongue.
Locate the long bolt in the kit, place through the holes and tighten securely.
Note: With our adjustable shank fitting also use the two smaller bolts supplied
to bolt the bar with the canvas flaps to the adjustable shank, the shank bracket
can face either way on the shank. (MKII Hayman Reese bracket picture below)
