Need an mk5 replacement piston for the old shoulder-less piston

[RyanNM]

Anyone have laying around the shouldered piston SP had as a replacement for the original piston that did not have the shoulder? SP made a replacement rebuild kit until about 12 years ago. I'd like to buy one if anyone has one available.
Or should I give it up and get an mk25?
thanks!

you might also try to post this in the vintage scuba section, might get more 'traction' over there.

Why again are you replacing the piston, is it damaged or is it just because the shop salesman...oops I meant technician....told you that there was a replacement.

There's no reason to replace it unless it's damaged. Even then many of them can be easily fixed as I mentioned in your other thread.
