Mythbuster: continuing project thread of my 1303 '75

Sounds like you should just measure yours, I did it by jacking the car as you have done above at ride height and holding an edge as close as possible through the points after having marked off the width of the tyre (before I took the wheel off) to get the centre line. Tie rods shouldn't affect scrub radius, just the affect of the scrub, their effect is more too do with ackermann & steering effort/speed.
