BTR Diff filler plug

[Mr Plow]

Hi All

Does anyone know the diameter of the plug on the BTR diff? Mine has started to leak so I want to replace the copper washer.

Cheers

Use a M12 x 15 or 20mm flange bolt, or an M12 sump plug.

I'm not sure on pitch though, it'll either be M12 x 1.25 or M12 x 1.75.

Apologies I cant be more specific.
