Removing tailgate components-- how hard?

[j-dogg]

I am going to buy an 89 (looks like 73-87 model) 1 ton crew cab, but the tailgate is in very poor condition. I was thinking about buying a tailgate shell and transferring all the latches, handle, and so forth from the old tailgate, but I've never done this. Is it fairly easy and straightforward or not? Any input is appreciated!
