Help decode this 4 speed transmission

[GrandpaKevin]

I've had this 4 speed buried in the back of my garage for many years and I am considering selling it.

I pulled it out of an original 4 speed 340 'Cuda back in the late 80's and I think the transmission was original to the car.

Can anyone verify what year and body style it is out of?
Thanks.

yes, the transmission would've been from a 1970 Barracuda/Gran Coupe/'cuda - SPD 710 - Wednesday 7/10/70
    3149 = Thursday 3/12/70 assembly date

23-spline?

Yes 23 spline.

That's a pretty late build for a 1970?

This one is an 18 spline.
