Did the Expo axle swap a while ago but now one of the rear seals is leaking pretty badly - getting oil on the rear disc (not good)

When doing the swap the rear dust shields were rusted out. Tried to source some two piece shields so I wouldn't have to pull the axle but couldn't find any, so just went without. Since I have to pull the axle to replace the seal, I want to put on proper one piece shields but having a hard time sourcing them.

Expo donor axle was a 2001 I think. Anyone know of a good source for this part?
