A couple of years ago I acquired a '98 BIRD (formula) seems the lad that sold it thought that I was blowing oil all over the firewall, it was! however just a PVC disconnected, 15 min. fixed. however the pass. door sags, thought it might be hinges but further inspection revealed that the passengers were using the door as a "crutch" to exit car and eventualy, sadly the door is cracked(broken) just above the lower hinge. has anyone had to deal with such a sad,sad situation as this and how/what to do shy of replacing entire door shell. THX for any help.

 

I don't really think you can do much to fix that if it is cracked. Can you post a picture of the crack?

 

without looking at it - i see two options
1. new door (obvious)
2. maybe fabricate a steel plate on the inside of the door that extends from upper hing to lower hinge. 1/4" thick plate should work - adds weight but it MIGHT be a cheap alternate fix

 

It's not hard to fix a cracked door at all. It took me about a day and a half which was mostly the setting time for the epoxy. Cost was about $70 for a quart which is way too much, but the smallest size I could get of the quality stuff ( at a marine store).
The hardest parts were removing the door and reinstalling it because I was single-handed. You remove the door, remove the hinge, sand the area to remove all paint, cut some fiberglass cloth to fit and apply the epoxy (do this for at least 4 layers. Then paint ($6 can from auto parts store) the repair area and reinstall the door.

In your case, you might be able to just prop up the end of the open door and remove the bottom hinge only. Then do the repair on the cracked area. Since it will be thicker now, you would have to readjust the bottom hinge mounting location to compensate. You may not even need to remove the hinge spring.
