Been tinkering with this 66 Collegiate I picked up the other day. Trying to get it dialed in so it shifts properly and now it won't shift out of first gear. The cable moves as it should. Wondering if this spring is broken? See where I'm pointing with the screwdriver, the spring hooks onto that little tab that sticks out. There another tab facing the other way, that looks like it should have the other end of the spring hooked onto it.
