Right drive shaft middle bearing/support bearing

In April there is a bigger rep. On my V70/1 bj98 Mj99. Since the right drive shaft has to be out, I want to change the middle bearing. NOT the inner or outer joint, but the bearing which is held with a blast ring on the long shaft! Skandix does not spit out a suitable over the fin ! In the Volvopower and Volvoforum yet no answer ! I puffed up the spare part number. Even better would be the bearing size or the bearing number ! Will certainly not be a specially made for Volvo warehouse ! I can get cheaper to good stock over my operation ! Need a number or the size ! With a picture !
