would appreciate if you could hold on to the C500, C100 and C203 connectors with lots of wire left.
All yours. The interior side of C100 was cut-off short, but there should be enough there for solder & heat shrink. C500, C203, and the front compartment side of C100 all came away with good lengths on them.
I can run them out later in the winter with the rest of the L67 build parts, or box them up and mail them relatively quickly. Take your pick.
