I'm betting this one had a trans-go spring between the 2nd Acc piston and the separator plate - given the pic below from when I opened it up back in August.

Your above comment didn't soak into my head until after I'd driven out the 2nd Accumulator pin and staked the ball from the Sonnax Pinless kit into the housing. I didn't think it would be a good idea to try and go back, so I went ahead with the Sonnax Pinless piston and the original unbroken spring, as per Sonnax's '94-Later instructions (spring in the Accumulator body, then Piston with dome toward the separator plate). Do you see any issues with that setup?

FWIW, the Trans-Go springs are a tight fit into that Sonnax piston, no wonder they can break.
