It was available in many GM cars starting in the mid-60s and was in use until at least the mid-70s. Sorry I don't have more detail, someone will offer more I'm sure.

I had one that came out of a Camaro and another that came out of a Vega. They were available with different gear ratios, and you might want to research the ratios and decide which version you want before you start searching. The number of grooves in the splines on the input shaft tell you which version you have.
