Comments on MC pistons please

[Jim Haseltine]

The pistons in my MB were identical to the one pictured after my engine
wreck and there was no way that I was going to reuse them, especially after
I measured the bores and discovered how close they were to needing to be the
first oversize. Managed to get new OS pistons from a Mahle agent - approx
$110 each.

Regards,

Jim Haseltine
