SK 45412 - need some help, hexagonal bit size

[Shelbylex]

Good evening

I recently got SK 45412 at the yard sale. It is missing 3/8 hexagonal bit. I am planning to cut a piece of allen wrench as a replacement. Can anybody open their socket (it's a small hexagonal screw holding the piece from the side) and measure me the total length of the missing piece?
...If it's too involved, can anybody measure how far the piece sticks out from the socket edge?

Thank you!

I may have one. I’ll have to check. Give me a couple of days.

I checked and here is what I have. The S-K 3/8” drive on the left is a 5/16” rather than 3/8” but likely the same length. The 3/8” on the right is a Proto and is shorter than the S-K.
