Shift linkage/shifter needs adjusting......SAFELY go under the car and put the 3 shifting arms on the trans. into the neutral position.

There is a specific procedure to adjust the linkage.

First, support the car safely on jack stands or ramps, with the wheels chocked to prevent any movement.
Place the shifter in Neutral
If your car still has the column back-lock linkage, you need to loosen the swivel clamp at the bottom of the back-lock rod.
Loosen the jam nuts on the shifter rods.
Insert a 1/4" diameter gage pin through the shifter housing to lock all the levers and the shifter handle in the neutral position.
Position the shift levers on the transmission to the neutral positions, then adjust the shifter rod lengths as required to perfect align the rod ends with the shift levers.
Tighten the jam nuts, then pull the gage pin and verify that the shifter and rod adjustments are correct.
Finally, if your car has the reverse lockout, put the shifter in Reverse. Rotate the lower steering column lock collar to allow the igntion to be rotated to the "locked" position. Then lift up on the back-lock rod to remove the slcak from the linkage and tighten the swivel that you loosened at the beginning of the process.

If the shifter is located properly in the floor opening, that should do it.
If the shifter is NOT properly located in the floor opening, there is another set of steps required to re-set the shifter properly on the shifter support/trans bracket.
