<VV> Fw: mic-ing my rod bearings (1967 Monza 110 PG)

Are you sure the piton is missing some part?  They do have a large hole behing the oil control rings to allow oil to return to the crankcase.  With the rings and spreader out one can look straight through.

I calibrated the mic (with a 2" piece that comes with it) and it registers
exactly 2.0005" ~ just a tad past the '0' mark at 2.000"  I'll try to find
some other 'benchmarks' to see if it's as accurate at other points ...

Still looking for the missing parts of the piston, but so far, they're are
nowhere to be found !
I have found the broken rings, but no piston parts ?
