An easy way to set toe in is as follows:
Buy a length of aluminium angle or box, say 25mm x25mm. Cut 2 pieces twice the precise length of the wheel's diameter. Attach each piece with bungees from the rear edge of the tyre, facing forward, through the centre of the wheel (over the spinner). When both sides are set up, take your measurements....the measurement across the front edge of the wheel, will effectively be the back measurement, and the measurement at the end of the angle/box....a diameter measurement forward of the wheel will be where to take the second measurement, of for example, no toe in, or say 3mm toe in, 1.5mm per side. Keep the aluminium pieces in a safe place enabling measurements as required.
