It is clear to me that I will need a replacement door on the right-hand side of my 1966 Mustang Coupe, since my Dad told me that a couple of years ago he had to poke through the little holes in the bottom to let the water drain out, and I can flex the opened door and rust falls to the pavement!

!
My question is, how much should I expect to pay for a good, solid used door, and what should I get for that price, ie; window regulator, glass, etc.?
Does anyone make complete reproduction doors?
Thanks,
Eddie
