Not sure how different it is from the later ones, but on mine which came off a '55 car, the "track" is nothing more that a thick nylon rod (no teeth). There are a pair of gear driven pinch rollers that grab the rod through tension only push or pull the rod up and down.

If the motor runs, but the antenna does not move, then problem is one of three things:

1) One of the gears that drive the pinch rollers is stripped.

2) The tension on the pinch rollers is to loose (this can be adjusted) and it slipping.

3) The nylon rod itself is broken or bound up on something.

Replacement parts usually have to be salvaged out of a another unit.

Luckily on mine, the motor armature had shifted in the housing and was binding, and I just needed to realign it. Everything else was good.
