Replacement of small pin

[fshnfool]

Has anyone had to replace the pin that locks the cockpit seats in place from Swiveling? Not sure if I can get just the pin or I need a whole mechanism. Seats are the original from Factory. 2016 gulfstream.

A pic may help.

On the boats I have owned, the rotating ( swiveling ?) is controlled by a know you turn to loch the seat to the pedestal. The spring loaded pin is often there to lock the seat height position.. I don't know if that applies to your seat but take a look for knobs that tuen ( or should turn)
