doors interchanbeable?

YEs and no.

They will all physically bolt up, but a lot depends on the power of the doors.

Try to find someone who has the same power options. Some time the harnesses will not match up, or the door panels will not fit right. Get a dremel with a flex line attachment a number of little cutting wheels. Cut the door pins and get a buddy to help you remove the old door.

Then get the new door pins set from 5.0 resto and have two friends help you put the doors in (they are heavy and it takes a little time to get them to line up.)

THen put in your new bushings and pins.

THe doors might not line up properly. If this happens take off the fender wells and you can get a wrench in there to adjust them.

Hope this helps
