Pintle hitch adapter for pelican sled

[Tjames09]

does anyone know if there is a conversion or adapter piece for pelican/otter sled hitches that work with pintle style snowmobile hitches?

The pintle hitch on my sled is 5/8" and the hitch on my pelican is 1/2".

A very long time ago when I still owned a snowmobile, I put a trailer type ball on the Skidoo, and a coupler on the sled.  It was kind of a Red Green setup, but it worked.
