1903 question

[venomballistics]

I am in the process of adding a ladder sight from a 1903 springfield to a 45-70.
The parts I have came without screws.
What is the thread pitch of the cap and slide screws?
from there, Ill just lathe turn my own parts.

I suggest posting your question on the Culver's Shooting Page. There's an 03 board there that will help.
