The 2008 receipt lists the M5 rod bearing bottom part number, and I think that might be because the parts list wasn't yet available. ??? But I do know that realoem lists the 1702 bearing as the only bottom bearing ever used on the S65, and the 1703 bearing shared with S85 and S65 during the entire production run.
S85 uses the same blue rod bearing (top shell: 11 24 784 1703) as S65, but has a different red bearing (bottom shell: 11 24 783 8088).

when you did the builds did you measure shell thickness and height on the red vs blue. What is perplexing and I have brought this up before is clevite paints those bearings, I have a entire drawer full of red blue yellow and green bearings at work that are painted in the exact fashion. The red shells are standard and the blue shells are +.001, yellow is +.0005 and green is -.001. This is clevites standard system. If that is not the case here it is baffling why they would paint the shells when there is no difference. Also if they were the same size why would there be two part numbers?
