recently I purchased a 96 scrambler that was in decent shape. In going through it, I noticed the front right shaft boot was badly torn. I decided to replace the entire shaft so i purchased one from ebay after matching part numbers ect.

I get the shaft today, get the old one out and then,…..noticed that the shaft that came out of the wheeler has a long key way that holds the clutch assembly not the multi spline that I purchased. I also noticed that the bearings seem to be a few thousandths too small to fit on the shaft. Im fairly sure i got the right shaft in the mail so my question is what year and or model took a single spline/key way drive for the hub. Im guessing it took a doner from some other machine?
