My Guess later model Truck after 1970 with 4.10 gear ratio.
Checked eBay completed items and one sold for $64 but had no info at all for what it was for.

There are charts from GM that show when a particular combination of trans and wheel-tire size got a particular part number reducer. The part number is not one of the numbers you listed. you have to do a bit of google searching to cross reference the GM part number to the reduction number, in your case the .9444.
Here's an example for a 1970 Camaro,Chevelle, Nova 4 speed cars: http://www.gmpartswiki.com/getpage?pageid=12662 If you plan on actually using it, you would be advised to open it up and clean out and re-pack the grease. It dries out over time.

A friend here in Calgary gave me one that I used in the green 4:10 gear car I recently finished. They work well if you know what gear conversion they were intended for.

If you repack it with grease use a light grease. Otherwise the load can snap the tab on the drive gear clip inside the tail housing.

Are these also used on the automatic cars, mine came with 4:10 gears but someone put in 3:73 gears. If I return to the factory gears I will have to get a reducer.Thanks
