Looking for diana 27 spring kit

Since I didnt get a response here I made an account on GTA forum and got following replies. (the last link is for chambers and they have almost all the parts for Diana 27 but it is a UK website.)

Try calling either Vortek or Jim Maccari directly either one will be able to help you I'm sure They may ask you the wire diameter and number of coils so be prepare to answer those questions

While checking things, confirm the diameter of your compression tube. Current Dianas use a 28 mm tube. Older ones used a 26 mm compression tube. If yours is old enough it may even have a leather piston seal.

For the spring, wire diameter and number of turns are good to know, as well as the inside diameter as it will have to fit over your spring guide.

Here are some links:
