volvo hub seals

[aidank]

hallo,

looking for hub seals for a Volvo L30, 1992 reg,
axle number is BRA8 000 A3 CZE,

I understand from local mechanic that the same hub seals on L30, L50, L70, L90

The original volvo part number is 11991937 and this seal has been upgraded to the following volvo part numbers

Seal Ring 11995030
Wear Ring 11995031

anyone got original manufacturers part numbers for these or know how do I link back to original manufacturers part numbers

or anyone know where I can just get the things

thanks
aidan
