VoV lists Jim Carter PN MEB994 as rear outer bearing for the G506.
So far I have not had much faith in the x-ref from that site.
But for $62 FOR THE SET (I assume that's a cup and cone) its gotta be looked into.
Rear Wheel Bearings 1936-1957 Chevrolet And GMC
Item Number: MEB994
Retail: $62.00 SET
Anyone use/have success with these??
