Folks, got a 216 stovebolt with 3 spd transmission torque tube rear, gearbox has a crack and leaks, differential also leaks, all original engine/transmission/diff to the ute.

I have a 55 open drive diff in my shed for a conversion to open drive

Does anyone know what’s involved in fitting the Packard 35-37 3 speed up to my engine, been told it was a common conversion back in the day

Steve
