There isn't really any tricks to it. If its metal, anything can be replaced. Look at the tracks and sprockets these may need to be changed. Motor and tranny, you won't know unless you tear it apart. Then just the body condition. As you can see from our rebuild, it didn't really matter what the sheet metal looked liked, she all came out anyway. But I remember you saying you didn't have a welder. If you are going to get serious and buy a metal machine, you had better be getting a welder and plasma.
