I'm looking for some new doors and I was wondering how do I remove the old ones? Are they bolted on or welded on? Any special techniques when putting the good ones back on?

 

The top hinge is bolted on. The bottom hinge is on a pin with bushings. Make sure you have someone help you take the door off and install the new door, these doors are extremely heavy. Also dont forget to get a new set of bushings (maybe a pin too if yours is worn) from your local auto parts store.
