When you have your replacement hinge in hand, you will see how the adjustment works. Unlike old cars where hinges can scoot around a lot, the FWD GP does not have a whole bunch of play. I don't think theres any adjustment where door and hinge meet. But where hinge meets car, just the big bolts hold it on. The little bolt holds an offset cone to the hinge that fits another hole in the body. Works like a cam... leave the other bolts a little loose and turn the small bolt to set the hinge's position in relation to the body.
