I agree with Weasel, the M II is too light duty for that heavy of car especially of the roads are rough. I would look at a Camaro clip. Just because they make it, does not make it right. Also many kits for the M II widen out the cross member moving the pivot points farther apart. Then they just lengthen the ends of the tier rods. This will give you more bump steer. I designed a narrowed M II front end for 1940 Fords. Could not find a proper length rack so had to go to a custom unit from a dirt late model, made to my specs.
