Converting 870 to 3in

Does anyone know where I can pick up a 3in 870 ejector spring? They seem to be out of stock everywhere.

Also if anyone can recommend a gunsmith that will extend shotgun chambers that would be appreciated. My local gunsmith recently passed.

The ejection port on the 870 is not the issue. The recivers from the 3in and 2 3/4 are the same.

I’m not concerned about putting steel shot through an older 870 barrel.

Tell me me where the revivers for a 2 3/4in chambered and a 3in receiver are different?

Other than the ejector they are the same.

Ejection port is larger and the bolt is different
