02 TB rear backing plates and bearings numbers?

Seems my backing plates are rotting away so I figure I will gather all the parts needed including the bearings and seals. I searched Rockauto and see many different bearings. Anyone know which ones are needed? 02 TB LS G80

If your gonna do that then just a bearing and a seal at each end... While your at it throw new ebrake hardware at it too...
