My 70 doors have a decent bit of rust and and some old repairs that were going to make repairing them a small fiasco. I was recently able to pick up a pair of 71-72 doors that seem to be rust free. Are the only differences between the different model years the mirror style and location? Are there any other gotchas I need to watch out for?

Edit: I should note these are hardtop doors
