I have to tell you the truth RED, you seem to be doing pretty dang good for not having done this stuff before..
I think you can probably make that rear lower door jamb. You might have to make it from multiple pieces... the problem with getting another trucks parts for this repair is most trucks have rusted there, at least on the back of the metal.. and if they haven't they are probably to nice to chop up...
EVERBODY can work/bend metal ...the question is where are your skills now.. we all start out with the ability to bend a 90 degree in sheet metal using a vice or similar. You need to look at it and think, what can I do with flat metal and forming over a object, what can I bend a simple flange on? sometimes you can metal from other objects that are close...
Most of us don't have a real anvil, but if you can clamp a part down good and work edges of the tin, over the object below it.. you might be surprised with the results and you WILL learn some things.
A artist with steel can make complicated parts that flow and bend like anything they want. guys like us can always cheat a bit, if the metal is bulking, binding, making unwanted waves.. cut a slit with a thin cutting wheel , and remove that excess material. once you work in the shape you want you can weld it back together.
One of the most important things i learned watching a friend was this, when you are making complicated ares like the bottom door jambs.. if you get you parts close, tack them in place with spot welds in the places that line up perfect, then you can take your body hammer, or ballpean hammer and stretch that metal around,Always go slow while you are watching and learning, sometimes you have to wail on it. I almost got mad a few times watching my buddy pound away at a repair
it is thrilling when it works for you, every time a new part of the piece lines up correct, tack weld it down. I was literally shocked a few times with my final results.
If you weld it up good, grind the bad spots,some bondo and paint will make it look nice. Personally, I like seeing a good solid repair on a vehicle whether it is stock looking or not. If you are a true purist.. it means you must strive to an even higher level of finish, and skill, and achieving skill is an honorable thing in every aspect of life.
