I measured the piston skirts at 64.01mm
Service Limit is 63.815mm


I am just working out what parts I need. Measured the ring end gaps.





Older (second ring marked with an "O") top 0.031" sec 0.05" easy


Newer (no markings on rings) top 0.029" sec 0.048"

Noticed oil ring variation.

So it is looking like I have 2 worn pistons and worn out ring sets, with both cast iron bores holding up well.
