Dana 44 ford front questions

I bought a 2dr cherokee with ford hp d44 and 9 inch in it. But the welds are terrible. I strted grinding the junk off and im going to fab and weld new brackets and links. But i dont know axles well. Are my wedges cast in or welded in? If there just welded, does the axle tube run all the way through or will i have to cut em out and re sleeve it? I dont want to retube it if i dont have to.

Heres what iv got pictures of currently.









Thanks for any help
