towing 4 speed dart with Tow bar

The FACT is that you must refer to the destructions for the particular car

On older vehicles with a "stick" whether 3, 4 5 or 21 speed, the cavity inside the input shaft where the mainshaft meets in roller bearings DOES NOT get lubricated very well

The only thing turning in neutral is the mainshaft and the syncro assemblies. The input, the cluster, and the 1, 2, 3 gears are stationary

According to the 72 shop manual:

This does not specify stick or auto

Not to mention the fact that since only the output shaft is turning there is no oil being thrown around, so not only is the input shaft not getting oil when spinning because of no lower shaft (counter shaft) gears throwing the oil around when being towed, the input to output shaft needle bearings will dry up and seize together at hwy speeds.

Trust me, I know this for a fact.
Undo the driveline and get an output shaft housing plug for it to kepp any fluid in, and road dust out.

I'm sure someone will argue that they have done it before and nothing bad happened.
You want to risk your trans on that?
