So you want hinged Land raider doors that open? Well here's how you do it.
First start by converting the doors that come with the kit. One of them is a normal door with a double eagle and requires little conversion. The other, is a door to access the ropes/computers panel that's included in the kit. I personally want all 3 of my access points accessible and ditched the ropes/computer panel. That door however needs to be converted.
Start by shaving the skull icon off of the outside as it will be upside down when you are through. Then place a small wad of green stuff on the inside, about center. Take the other door (the good one) and put baby oil or lotion on it. Sandwich the two together and apply good even pressure. Separate. You should now have a diamond pattern impression on the door you are converting. Clean the lines around it and now it is a respectable door, not an access panel.
After that, put the door in the frame. Run a small wire through the inside of the tank door frame and into the door's hinge. Once it will go no further, bend the wire around and glue into place. It's a good idea to place some blu-tac over the hole the wire runs through so you don't glue the door in place (and ruin you work).
Once this is done to each side glue a small extra peice of sprue in the shallow track below the door frame to "block" the wires in place. Once the glue dries, you can remove the blu-tac.
