72 gmc front crossmember swap?

[jr3381]

I have a 72 gmc short bed 2wd, I have it stripped down to the bare frame with the front crossmember still attached. I have noticed a few tender spots in the crossmember and would like to replace it. the brackets on the top of the crossmember that attach it to the frame are thin and the bottom of the member itself has some weak spots. will the 73-87 crossmember fit? I am under the impression that it will. I have already purchased the upper and lower balljoints and inner and outer tie rod ends if I swap it out to an 73-87 will these parts fit? any help would be greatly appreciated
