Help, Canary Yellow project

[Mrmerlin]

Hi I am looking for A set of pistons for an 88 928 S4 tolerance group 1. They are for the Canary Yellow show car, I hope some one could help me. I could use pistons from 87 thru 91, used in good condition . Donations accepted, Thanks very much, Stan
you could call me at work 801 487 6733 Ask for Garrity or Dave
Also as a side note the pistons that came out of the car have 2 holes drilled in the skirts below the piston pins anybody know what these are for.

The original pistons got cleaned and by mistake the factory coating of chromium( the light green tinted color) was removed from the sides of the pistons.
Project is stalled until pistons can be procured Thanks again ,Stan
