Is my drive shaft toast?

[spudz]

I pulled the drive shaft from my 79 c30 today to replace the u-joints. Upon doing so, I could slide the carrier bearing off the shaft! I know this bearing is pressed on. Maybe someone turned it down? or a hacked old repair where the bearing ate it out? I dint know. I just know that your not supposed to be able to slide it on and off. I bought a new carrier bearing and it does the same thing.. you can see in the pic, the area on the left is smaller then the little 1/4in space where the spacer ring goes. you can see the line. Sorry for the crappy cell pics, I didn't have my camera at work. Is there anything I can do short of finding a new shaft? Anyone have the front half drive shaft in SC they want to sell? just my luck... oh well. :-(
