Bought this used SA factory tow hitch for my Doka. Unfortunately, it didn't
come with a towball or receiver. Thought I could just get a bolt on towball
or receiver but apparently the bolt pattern is different than the
domestically available units. I have a pintle hook from my European hitch
with bolt holes matching the pattern. I can only assume it's some standard
metric size.

Does anyone have one for sale or have some idea where I might find one?

TIA,
