tilt column ?

[wibilly]

i have a van tilt i'm putting in my truck, problem is somtimes it don't want to go from drive to neutral reverse or park it will if i srand it on the wheel end but put horizontaly no go.is it that the lever is warn and not pushing the detent in far enough?when i take the lever off it looks like just a spring it pushes on is there somthing missing? i took it out of a van some time ago and don't think i ever tried shifting it then, i just checked it for slop in the joint and bearings. any ideas? i tried different levers but none seem to be the same on the inner end. i'm stumped!
