chevyb - The P/N 32364 on the box is the original manufacturer Eaton assigned number. It corresponds to GM# 2279003. A search of
GMPartswiki for "2279003" links to about 10 or more Chevrolet and GMC Master Parts lists/publications were you can find the end application info for this 2 speed electric shifted axle screw.
Below are just some screenshots from some of the listings to show the variety of applications. It's even listed in a later School Bus parts book as they apply to some of those models as well.
I think our "Big Bolt" owners with electric shifted 2 speed rear axles could find this offer most interesting. They can do the same search I did, or just look through the pictures below to see if their truck/buses fall into the application list for this part. Best of luck on your sale!
