One thing that Landies are bad for is the wheelbase being different side to side too.
On open wheelers we'd make bars for the front and rear that pip pinned or bolted into place at hub height with a slot equidistant ether side of the centreline for the fishing line so setup was bloody quick, and if you'd already sorted bump steer back in the workshop you don't need a dead flat surface either.
