Slick 60's

Of those you whom have completed the crown vic suspension swap....how far forward did you move the axle center line?

how low you plan to go has a little bit to do with it. the lower you go the more you move it. just going crossmember to frame 1.25-1.5". cut coil(s), bagged, etc 1.5-2". so if you want a safe middle ground figure 1.5". no use trying to get perfect since you're putting in a suspension thats 5" to wide................

It would also depend on the year of your truck.....the centerline of the '65/66 is already moved an inch further forward than the previous models.....

Pictures and info on your wheel choice.
