I am posting this for my dad. He has a 65 with a 289, 4 speed toploader. he installed a hurst competition plus shifter. He was unable to shift into reverse. The shifter was all the way in the reverse position, he went underneath and the reverse knob(sorry I dont know the specific term) on the tranny needed to turn 1/4 of travel to engage the reverse. He adjusted the linkage so the car was in reverse. He then shifted into first and it would not come out of reverse. again he went underneth and the reverse knob needed to travel 1/4 of the way in the other direction to disengage reverse. What is the cause of this? The reverse shift rod cannot be adjusted to accomodate both states.
