This is a Spicer gearbox from a mid 90s Honda 4 wheeler.

This came from an estate I helped clean up, so I know very little about it.

The paint is peeling off from corrosion, but it turns nice, and the splines look good on the input and output shafts, I don't see anything broken. I think you can clean it up and replace the seals and it will be good to go.
