WANTED: Capstan winch parts

[Clausnam]

Hi All,
I am new to the site. I dont own a GPA but thought I'd try and approach GPA owners in hope To locate some missing parts..
Since GPA's all had capstan winches equipped as standard issue I was hoping to find members that perhaps own or purchased a complete capstan setup for a jeep but only used the winch for the GPA. I am looking for the drive assembly parts, to connect the winch to the crankshaft on a jeep.

Should anyone have any parts please pm me.

Much appreciated
Claus
