Technical Drag Link Steering Geometry Diagram

I recently bought a Model A roadster pickup that has a suicide mount behind the axle spring setup with split wishbones. The work in general on the car is good but the steering has kick back on bumps. Somewhere here on the HAMB on a couple of threads on front end setups people had posted diagrams of correct and incorrect steering geometry for drag link type steering. Can someone direct me to this info or post it to this thread? Thanks.

 

Look up "bump steer" with the search option.
