The issue I have is the good body is an inline 4. Has leaf springs, and not a LSD rear end. So would it be better to switch all that out or replace the body?

I am thinking that I would replace everything except the body so why not just do that?
Again, I am asking as I have never jumped into something like this.

Thanks

Hate to say it. Never have time and money together. The raiders all of them are available.
Parts or whatever you want.
