Help needed to identify piston

[danscoauto]

Hey all,

I need a little help identifying these pistons as I have never seen them like this before (picture attached).

Was told they came out of a JDM Galant VR4 but have never seen this style of dish on anything 6 bolt before so it has me curious and I'm scared to use them on my 6 bolt in case they are actually out of some weird N/A Mitsubishi or something.

Anybody able to help?

Thanks in advance

They are aftermarket, and kinda look like diesel pistons , thats as best as I can tell, whats the skirt size on them?

Those are E33A Galant's 10.4 compression pistons (Non turbo 6 bolt 4g63, including Galant AMG).
