* I have a 94 Caravan (short body) and 2 of the doors are all rusted and disintegrating at the bottom. I have a line on replacement doors from an old 94 short body Caravan but my concern is this - I have power windows and locks whereas other has manual. Does anyone know if these doors are identical in construction and can be retrofitted?

Would it be a matter of taking the inside panel, controls etc. of mine and attaching it to the outside panel of the other doors? Any help on this is appreciated!

Also, does anyone know why these doors rust down at the bottom? Exterior wise they were fine for the longest time - looks like an 'inside' job but I don’t understand how it happens. My passenger door is just fine.
