electric pony motor starter gear/belt pully bearings....

so....was wondering if you guys would know how to find the numbers for the bearings in the gear/belt pulley...thingy...that the starter goes into for the pony motor.....started my D4 up this morning and the bearing between the gear and pulley itself....well....hand grenaded in a shower of sparks and metal ....pretty sure I can get the bearing at a local parts house if I had the numbers.....also need numbers for the little bearing on the back side of the gear

The inner bearing 7f8660 and outer 7f8661

7F8660 = Bower/BCA 201SS
7F8661 = Bower/BCA WC87504
