Stuart Tank Trailing Arm Pin Extraction

[Andrew Rowe]

Has any body out there extracted the pin from a Stuart Tank trailing arm?
It is the pin that holds the two cast arms for the main wheel.
This pin goes in the main casting that is bolted to the tank and has a slotted groove on the outside face
This pin appears to have a thread on it.
Is it threaded all the way through the bushing in the housing??
