Sonnax Billet Accumulator Piston Install 68RFE

I recently switched to installing these in our valve bodies instead of a different brand, and I can’t get them to fit. I’ve tried lubricating them but they just seem too large, the guide seals are too big. I see something about “sizing” them, has anyone else installed these pistons that can give me some input?

Hi did you measure the valvebody bores then measure the pistons? I think some are different sizes.
