The yoke is basically part of the shaft and can not be replaced.The U joint can be replaced if the yokes are good.The only option i know of for the damages yoke is filling it in with weld and re drilling it out.I cant remember if it is a cast yoke or not so your only option is to spend to 100 bucks for a new shaft.
If you remember how did you get the snap rings to seat? I bought a 392 u joint for the front and it’s a little bit bigger then the original, when I put it in the yoke there’s not enough room to seat both snap rings.I never had to replace the rear one but did do the update to it with the rubber ring and stop- courtesy of Kubota. That was probably back in '06. The front one I replaced like 3 times in the 4000 hrs I had it- last time with Marks 392's u joints instead of buying from K.
