Worth looking at some of the work the late John Miles did on Austin Seven steering geometry — notably to reduce bump steer and to improve steering control over uneven surfaces.
I have his mod fitted to both Special and Opal - basically a 20% extension to the steering arm in conjunction with use of rose joints for the linkage.
This seemingly small mod makes a big difference to handling and, particularly on the special, contributes a lot to the enjoyment of driving it purposefully.

Looked up this John Miles mod, and tome it would slow the rate of turn as the link length , drag link to king pin is increased . Would this possibly reduce the steering lock ?
