I was given some Bogen/Manfrotto lighting 3078 & 3082 stands and smith victor lights.

Apparently hauled home in someone's pickup as some damage ensued.

One of the light stands has a 1/4-20 brass stud that appears to be pinned into the top of the stand, not immediately evident that it comes out.

I did some searching and found nothing on parts for these. Can anyone tell me if this is a replaceable part?

I can see options for hacking another solution if not.

Thank you
