Topic: Front Parking Lamp Housing Removals

[midlife]

I was provided a 1973 light harness for restoration, but it was missing the RH front parking lamp.  What remained was a standard pin with a locking tab, but the tab was missing, bent completely backwards and torn off.  Examination of the LH lamp shows these pins go into a boss on the back of the plastic housing, but there's no access to the locking tab to remove the pin.  Does anyone know how to remove these pins?

I have extra housings, and would like to remove the pins and install it correctly, rather than splice the wires.
