Replacement SVT-40 gas piston parts

[GunsNotPuns]

A few years back Corwin used to carry stainless steel gas port kits for the SVT-40 but I haven't seen any in some time. Anyone know where a chap might find one these days?

Haven't seen them anywhere else for a long time.

I saw that page during my search but missed he shipped to Canada. My thanks!
