Attention detroit gearbox or any help with p/g input shaft

[87stang]

Can anyone/Rich help me out with the makings on this P/G input shaft
Marked TCILeft side looks like a 4 over number 11
Right side a T over the number 86

What do you want to know?
Its a powerglide spline.
The length determines which planet it fits.
12 7/8" fits factory 1.76
12 5/8 fits factory 1.82

Most TCI shafts I see are 12 3/4 (which is in the middle)
They must figure thats close enough...Lol.
If you need a new or used shaft I have several in stock.

It's not twisted like one ones I have!

Does that help you at all?

Hahahaha
