i hear ya , i took me many hours of playing with mine the key is to center the nose carrier. then distributr the error across all the slotted parts. it took me a while but mine is real close . For somereason my right fender is lightly bent upward. i may use a 2x6 with lots of cloth to to protect the paint. jamb the 2x6 againt the ceiling , then slowly jack the car up.until it pushes the fender corner down..
