The 6 side bolts into the chassis rails are all M10 X 1.5 in any length from 25 to 40mm.
The 2 bolts that go up into the rear X member are M12 X 1.25 and are about 75 to 80mm long. They are available for less than the price LR want for them.
My tow bar is fitted. This is the correct bolt sizes.
Ones again thank you.
