Stem Bearing size for 1980 GS1100E

[andler2008]

can someone tell me what the bearing size is for a 1980 GS1100E? i have to buy a set of bearings for my triple. all balls says the O.D. is the same from top to bottom. but i know that the bottom is MUCH bigger than the top. so now i'm stuck.

Measure your old ones to make sure.
