Muncie Input shaft Course 10 Spline 26 Tooth Identification M20 or M22 ?

I dont think thats a Muncie 4 speed input, see the small protruding register on the front of the input just in front of the in mesh teeth? notice it has a small oiling hole? Muncies did not use this, also the machined register for the main shaft in the back of input appears too small to accept a Muncie caged input roller bearing assembly, it kinda resembles a Borg T10 design in which the rollers were individual stacked. I think its a aftermarket 9310 input.
Can you post a better larger picture of part number?

Here is that larger photo of whats left of the Part # I also re counted the gears and there are 27 of them not 26. Still a 10 count spline.

BINGO
A guy on a FaceBook Transmission page recognized the number being 3855734 on the box and a google search tells me it is for a 1963 only Borg warner Corvette input shaft. Mystery is solved. thank you Everyone.
