Now I'm no expert but I would first make sure the car was on the tires not jack stands or on jack stands under the rear axle and by the ball joints. I would then make sure you replace the door bushings and pins. Then enlist a friend for help and attach the door to the lower a-pillar loosely and support the back of the door with a jack with a rag on it to protect the door. Then close the door adjust the stricker to the desired position and totem the door hinges to the body. Then I would bolt the fenders on loosely and place the hood on it. To align the hood gap well aligning the door gaps.
