Tuning Walther LP53 Tune

[Townsniper]

Hello dear 

I'm new here 

I have my own Walther lp53 without any modifications

I want to know the exact detailes about how to upgrade the spring ,the seal and the piston 

If these parts can't be ordered online so I want to know the exact dimensions and specifications to be able to make them 

Regards

I want an accurate data about the detailed dimensions of the PTFE head seal of the piston to be able to make it with a lathe machine
