I recently purchased a B7610 and hoping to install my old snowblower (a B2650) that I was told came off a B7500. The snowblower fit my B7100 with only minor modification. The subframe fit the B7610 again with only minor modification however the mid driveshaft is about 5 inches too short to be safe to use. After some searching I found many new driveshafts are fixed length. Does anyone know if the fixed driveshafts have the same Kubota proprietary spline on both ends? I bought a proper length shaft locally only to find I am now looking for the Kubota splined slip end. Trying to find what snowblower model might have the shaft I am hunting for. Thank you for your time.

If you cannot find what you need, what I would do is take your driveshaft to a competent driveline shop like Custom Clutch and Joint and have them lengthen it to the correct length.
They will weld in a piece, make sure it's straight and true and balance it if need be.
I've done a few in my shop for my personal use but you need a professional driveline shop to do it.

On the three examples I own, they all have the same type of spline on the quick hitch, and they all have the same type of spline on the mid PTO of the tractor. BUT the tractor spline is quite different from the quick hitch spline, with the quick hitch spline having more flutes than the mid PTO spline.
Sorry, I know that's not what you wanted to hear. I think Flip's suggestion is likely your best way forward, short of getting the right Kubota part.
Last evening I took the safety covers off my old driveshaft and found a few things interesting. My old driveshaft has a rectangular slip joint but only about 2 1/2 inches of the female section are rectangular.
The old driveshaft slides just over 3 1/2 inches together giving me complete engagement. I have always wanted 8 inches of engagement however not sure it matters in this case.
The second item is both the fixed shaft I just picked up and the old female shaft have the same tube making it easy and cheaper to have the driveshaft lengthened at the driveshaft shop.

That's a positive finding indeed. Let us know how the lengthening worked out for you!
(Only guys would talk about lengthening their driveshaft... LoL)

Like the old saying... "An inch longer and I'd be a king. An inch shorter and I'd be a Queen"....
Finally hooked up the snowblower without lengthening the original drive shaft. There was a fair amount of vibration in the length of the mid driveshaft but since the cover was reinstalled I will have to remove the cover and test it again. If there is still vibration I will look into installing a center support bearing or bringing the driveshaft and having it lengthened.
Adding a center bearing was cheap and easy. I used a 1 1/2" self centering pillow block bearing purchased locally. The bearing slid snugly over the end of the driveshaft and had 2 set screws. The support is bolted to existing holes in the loader frame.
