Did Chevy produce a locking rear differential or something similar to 'posi-traction' in its 3100 or 3600 trucks of the early 1950's?
If so, how do you identify this type of rear-end?
Thanks! | | |

It also had a metal tag riveted to the dash saying "detroit no-spin, etc..". Maybe you can still buy the hardware from detroit or one of the other places that make locking hardware for the 4 wheel guys? | | |

The reason I'm asking about this is I seeem to recall (memory is the first to go!) seeing a diagram showing how to ID the different differentials by either the shape of the cover - OR - the style of rear hub assemblies in a vintage Chev parts catalog or the shop manual reprint. BUT - I can't find the source of this 'memory'!! :o)
Thanks again Don and thanks to anyone who has additional info -
