I would check the firing pin length first, and if it is .495 or longer, it should be good. I would be careful of putting one in that punctures the primers, that can damage the firing pin bushing.
I have an extra main spring screw from a kit that I did not use, that comes with an allen wrench. If you will send me an address by private email I will send it to you.
