Screw sizes for old style 3 screw trigger?

I'm working on an old 110 .243 flatback project that had a trigger without the sear adjustment. I located a 3 screw trigger with the sear adjustment on it and everything was going along smoothly. Entirely too smoothly for one of my projects I guess.
To my surprise the trigger I ordered arrived completely stripped with no screws or even the pin for the spring in it.
I'm pretty sure that there is a local "real" hardware store that will have the parts I need but knowing the sizes before trying to locate them would be very helpful.


Does anyone know the proper size screws for the Safety, Over travel, Sear, Trigger retaining pin, and the proper size roll pin for the trigger return spring to rest on?
This information would be greatly appreciated.
