Steve,
I would suggest when you're doing the inner sweeps to either reuse the existing holes or pre-drill them for the staples. The ivory colored plastic composite that is used on the upper door panels are usually quite brittle. Just be cautious. You breathe on them wrong and they crack.
I suppose you can also rivet them on. That might be safer than using staples.
When I did them on my 2+2 I used a thin blade screwdriver to pry open the old staples and a pliers to open the staple and remove the old sweep from the door panel.
Then I placed the new sweep on the door and clamped it to the door panel and drilled holes through the sweep and panel and reused the old staples. I then bent the staple ends over by first bending the legs over as much as a could with a needle nose and then clamping them with a channel lock.
Hardest part was making sure nothing moved when drilling the holes, you want slight pressure on the sweep pulling down for the reveal molding to be flush but you have to push a rubber flange down sightly so it deforms to the door.
Forgot to say mine didn't have holes.
Your going to have to do a good job putting the steel top part on your masonite panel and having the screw holes align.
I guess 4-dr/wagon door panels are constructed differently. Sorry about that.I didn't see any plastic composite on the upper door panels. The cap on my door panels is thin metal and I'm redoing the upper panels with new material and new backing. I using 1/8" hardbord/masonite. I have coated them with waterproof sealer since that picture
