I have wanted one my whole adult life. I finally get one: 87 Grand National. Only I can't afford a low mileage garage parked perfect car. I found one I could afford. Yes, it has a few issues. Yes, It has been wrecked before. I take it all with a grain of salt. The motor is strong, transmission shifts great, the A/C blows cold and the interior is perfect. The body has its fair share of door dings and a parking lot pole ding on the right rear quarter. I fix the tail lights, the brake lights, the dash lights, replace the bumper fillers, put new tires on it. But there is one nagging problem I want to get fixed before I send the car off to the paint shop: THE REAR END IS NOT CENTERED UNDER THE CAR!!!! Upon closer inspection, my car has been raped of the 8.5 rear end and has a 7.5-non posi in it's place. I am guessing the rear end was changed out when the car was wrecked. I suspected the control arms were bent from the previous mentioned wreck. I replaced the lower control arms, it moved the rear end over a hair, but not nearly enough to fix the problem. The rear end needs to move toward the passenger side about an inch. Am I completely screwed or is there a way to center the rear end? I am going to be on the hunt now for an 8.5 posi, but I have to get this car tracking straight.
