I'll see if he can get some. 77 ford hp44 i narrowed to waggy width with flat top chevy knuckles and relatively straight arms.
If i remember right good ackermann follows a path from the center of the rear through the balljoint to the tie rod?
Ackermann is a bit like pregnancy. You are or you ain't. But yes, a line starting at the center of the rear axle and extended forward to end at the center of the tie rod attachment point should intersect the center of the kingpin axis.
If he has highly compromised Ackermann, the result will be darty steering with a very non linear response to steering input highly affected by road surface and chassis weight on a tire. As in whichever tire has the most weight on it will impart the most steering output.
