Brownell’s has the T3 firing pin assembly in stock. I tried to buy one from them a year ago. I bought one from Midwest about 6 months ago now. I know others have been looking for one. Don’t know what their problems have been though. On my old T3 bolt, the firing pin is just about worn through at the cone and is ready to shear off. I don’t think this pre-mature wear happens very often though. You may be able to just replace the firing pin and the spring although I have not tried to do that. I replaced the entire assembly because the bolt was going into a new build.
