Mercury Repair Questions? Ask a Mechanic for Answers ASAP

What year, make, model is this?
Tape a tape measure and measure from the center of the right front wheel to the center of the right rear wheel, then compare that distance with the reading from the center of the left front wheel to the left rear wheel. It should be no more than 1/4". It it's over that the tracking is off and most of the times it's because the rear axle has shifted or rwd drive vehicles.
Let me know the readings.
what were the readings?
