just looked at a 63, got a bunch of questions

[68c10owner]

I went and looked at a 63 shortbed this morning. It`s missing the bed but I`m not too worried about that. Anyway, I noticed that it has frame supports in the rear that go to the rear crossmemeber. One of them is broke all the way through. Can I just remove both of them and build a crossmemeber to go across the frame rails like the later trucks? And the driver door opens up to the point where the door has a dent from hitting the fender. The guy has a 66 also and that one does it too but not as bad. Is that normal for these year trucks to open like that? He will also include the 12 bolt from the 66 he has if the 9" he got from a friend will fit. That will bolt up with no issues right? The front frame horns are damaged but I`m thinking I can just find a old truck at a yard and cut them off and weld them onto the 63 frame. It has a 350/350 combo but I don`t know if I want the motor. I can get it for $350 without the motor and bed. It also has what looks like a factory metal fan shroud. I don`t ever remember seeing a truck with a shoud when my buddy had these year trucks. Are those hard to find? sorry I have so many questions, just wondering if it`s worth picking up for a project. Thanks guys.
