F78 Fourtrak rear axle inner oilseal

Forum: 

I need to obtain an inner oilseal for an F78 rear axle (the one in the outer end of the axle tube that is visible when the halfshaft is withdrawn) As I am in Spain I can't order it by vehicle type as Daihatsu's don't feature in parts catalogues here. Does anyone know the correct size and specification of the seal? I can then easily get one at a general motor factors.I can get one from the UK but a well known 4X4 parts dealer wants to charge £17.25+vat for the shipping alone when the postage cost is probably less than £3!
