WTB A-727 23 spline Input shaft

[RW74]

Hey, all.

I have a 1985 727 Torqueflite and I want to put a lock-up torque converter in it.

Currently, it has a 24 spline input but the lock-up conver fits a 23 spline.

I have an 8¼ differential with 2:71 gears and the transmission runs a little too toasty for my liking.

I put a D150 stock Tow package transmission cooler in it when I swapped out the diff.

Anything helps.

It's not that simple

I already have all of the parts, other than the input shaft, to change it over.
