You might try some Austrailian parts sources since the Pistons were made for that market.

Autotec can supply you with a set of forged flat top pistons.
They will be a custom 4032 alloy piston made to your specs.
You get to choose piston pin size and height and piston ring groove size.
If you can get moly rings for this size piston then you can have the pistons made to fit the rings
This will also allow you to use an aftermarket "H" beam connecting rod.
