New member has a Ithaca Lewis project

Alcaviglia,
I just looked at the photos, you are a genius! I am not at my work bench but will be tomorrow. I will try to walk through your photos and instructions. If I get stuck, I'll surely be knocking on your Internet door again! I noticed that the forward screw for the Crass model seems to go 'through' the front of the mainspring. It would be nice if the Lewis had that as well.
When I get to the triggers and safety, I'll keep in touch with you if I bump into yet another challenge.
Regarding the screws that I want to replace (almost all of them!), do you have any sources of where I might look for replacements? I have died a few blanks, but the pitch seems a little off (mabe I should do a clean up tap on my receiver threads?) and the blanks that Brownells sells have slightly different heads on them and will need a fair bit of grinding for each. Original screws would be so much nicer...
Thanks,
Dan
