Where can you buy replacement doors for a 1991 honda accord ex?
 

My dad wants to replace a door on his honda before he sells it.But he hasn't found any yet.

Well it is from my best experience to call around to different scrap yards to find a door or doors it won't be as expensive and you can even try having the scrap yard look around for you and most of the time they can find you some so u wont have to travel to go get them if they find them at another yard bc they will look for miles away at other scrap yards....

try a wrecking yard that has a "pull a part" service. you can find new or nearly new car parts in these places.
