Oh, and because most Mogs are built on the pi55 (inaccurate chassis) all the above is a waste of time unless you set up on a 4 wheel laser jig and make sure the rear to front is parallel
With car on ramp I took a metre long spirit level and checked bottom cross arm for level. It needed about an ⅛" under lifting pads on one side to achieve this, provided by some old coasters. This took account of any chassis/frame error - I think
I then set steering wheel straight ahead having previously checked it did drive straight in that position.
Using spirit level and try square I calibrated the magnetic camber device to ensure it read zero = horizontal when clamped to a perfectly vertical surface. After clamping device to top of disc with kingpin fixings loosened I checked/adjusted camber. After re-tightening kingpin fixings I re-checked. Hopefully that covered all the bases
