Hi Gibbo
Ideally the walls of the radius arms should be vertical. However for the pre 1936 ones with just the single large threaded protrusion or boss the action of braking twists the axle forward and the radius rods if not very tight work their way off vertical to accommodate. Restoring the walls to vertical or a little beyond is correction / adjustment of castor. If the car is standard height and the chassis front not been bent the stock castor should be achievable.
Castor will not turn a Seven into anything resembling a modern .
Memories fade. My father had the use of my Seven about 1969, ten years after it had been his only car for preceeding 17 or so. Although with hydarulic s.as it was much superior to original he could not believe how bad it was!
Any stiffness in kpin bushes, track rod ends, steering box will prevent self centring after minor deflections and the car will wander endlessy.
