Help ID screws

[t3ttp]

I am rebuilding my transmission this week. I have the engine broken down and found that the t40 screws (4 ea) holding the middle gear bearing are stripped. I need to ID the size for this screw. Also found the 3 screws holding the main axle bearing stripped as well. I need to ID the size for this item too.

I do not have these screws out yet. I would like to have spares before taking them off.

I probably have new and or used on hand. The large head holding the middle bearing are very unique (I have plenty of good used ones). The smaller screws holding the case half and bearing of the primary shaft are more common (and what I have for sure new).
