so the hatch needs to go up or needs to move closer to the body?
if up, loosen those nuts and slide the hatch up a hair higher then it needs to be. stick a block of wood or something to hold it at the height. then go in through the back door and tighten the nuts back up. climb out and remove the block of wood or whatever is holding the hatch up, open the hatch, and close it and recheck alignment. if good, you are done.
if the hatch needs to move forward, the body side of the hinge should look the same, but under the headliner so you will need to drop the headliner to get to the nuts. same deal, loosen the nuts, slide the hatch forward, tighten the nuts from inside. check and adjust more if needed
