Have lost the key for the drain and filler plugs for the diffs on my F plate RRC. The callipers suggest that the (square) plug has sides of a little under 13 mm. Sealey supply drain key sets, e.g. AK658, with
3/8", 8, 11, or 13mm square keys.Does anyone know the actual size for the key? I suppose that I could grind the 13 mm Sealey key to fit.
Halfrauds don't sell anything even approximately the right size so I can't 'buy and try' from them.
TIA
Richard
