'67 Dart drag car with a rack and pinion swap needs some geometry help

unfortunately, the cheapest way to make it safe to drive is put it back to stock.

Your steering / ackerman issues are caused by the builder swapping the LBJ / steering arms side to side to attempt to mimic front steer spindles. To fix this, I would recommend using front steer spindles (Mustang II) but they are not compatible with a factory (style) K.

ackerman 101.... the inside wheel turns at a tighter radius than the outside wheel and is built into your factory steering arms. When the steering arms are swapped side for side, the outside wheel NOW turns at a tighter radius than the inside causing the outside tire to scrub or try to rollover the rim....not good.


The rack and pinion placement...... up / down / forward / back in the chassis is CRITICAL. Without proper placement, expect serious bump steer issues (car dancing around) whenever there is any suspension travel. The higher the speed....the bigger the dance. This CANNOT be "fixed" by moving the outer tie rod up or down unless the rack re: inner tie rod pivots are mounted in the correct place in the first place. Otherwise it is a dog chasing his tail.

Just trying to help with explanation, MHO....others may vary.
