Giant Reign 3 Suspension Bearing

Hey all,

I bought an old Reign 3 '05 last year and finally got round to rebuilding it.

When I took apart the rear suspension, the upper bearing (i think its called the seatstay pivot, refer to pic) both just fell in pieces. Not sure if that what those bearings are meant to do but never seen that before.

I have bearings for the rest of the suspension set up but need to replace these smaller ones.

Does any one know the model or specs of the bearings i need to get?

Any help would be appreciated.
