Markings (29B) on rear shafts?

Hey all, I've searched, but my search skills are lacking at times. I noticed "29B" on the ends of my shafts today. Jeep is '94, rear is 8.25. That should be a 27spline. There is also a stamp, which looks like a date stamp, of '95?

Can someone tell me what these mean, or at least point me in the right direction?

Could be a batch number, or maybe someone swapped in a 29-spline axle in to your heep?
Only way to confirm is to remove a shaft and count the splines.

Could be many things, but I can't find any info at all! I've always heard that you need to count the splines, so I'm just calling the "29" a coincidence. The heep was stock when I got it so its highly unlikely someone swapped in anything else.

Anyone? The shape (two flat and two rounded) appears to be stock. I only have access to my Cherokee, do they all have some markings?

I've worked at a axle shop for 12 yrs. Haven't seen this referenced to anything to splines before. Not sure.

Theyre casting numbers, but the only way to prove it would be to pull the shaft.

Best way to find the answer I would guess is to go to a junk yard and look at the other xj rear axles and see if they have that marking or something differet
