Hi. I have been through this before with the 9.75 rear end. To get the right axle you need to count the number of splines on the axle shaft. I would recommend not ordering the axle online because it is a good chance (unless they list how many splines are on the axle) that you will get the wrong one. I recommend going to a local part store and ordering it so you can verify that it will have the same number of splines.

I see you viewed my response. Do you have any more questions for me on getting the correct axle?

Seriously, why are you viewing my posts and not responding? I informed you on how to find the correct axle for your truck. If you are all set perhaps you should rate my assistance and close this question out.
