I am looking for two rust free doors for my 87 GT convertible. What would you say is a fair price to pay? I've gotten a price of $200.00 a piece from a salvage yard (specific to Stangs), and another on CL asking $150.00. How close is this to realistic? Also, I'm aware of the difference in mirrors, but since they are adjusted manually on the 87, would it make a difference if I replaced the both doors from a car of another year? Thanks guys.
