Roadranger input shaft deisgn change

I am replacing an input shaft on a RTO15613 and the replacement has less "meat" in the spline that goes into the input gear. This means a lot more slop between the shaft an gear. I thought it was a poorly machined aftermarket shaft, but the place I called to get an OEM shaft said that the Eaton shaft is looser also and it was a "design change". I can find no mention of this on the web anywhere.
Has anyone run into this? I am going to install the OEM shaft and keep the aftermarket as a clutch line-up tool, but I can think of no reason you would want a sloppy fit in that location, and plenty of reasons not too.

Kinda doubt it. For one, you would have to have the trans out and on the ground to check, and most shops I've worked in require a "clutch kit" be installed when a clutch is changed to get any warnentte on the job.
A Clutch kit contains a new shaft, bearings, bearing retainer, release fork, cross shaft bushings and gaskets.
I guess what I'm saying is the shaft gets replaced anyway, so not sure why you would want a looser fit, it would seam like it would hammer it gear more, with more clearance.

Kinda my point, We are of a generation and Mind set of make it right, make it last. New stuff, if sloppy, Will, as you state, perhaps cause more "wear" necessitating a shorter time between "repairs".
Just my thoughts and I could be way out on a limb, but, I see it in most all consumer goods from even 25 years ago to now.
