You will have to remove the sweptline's under the motor crossmember, the CV's crossmember will occupy the same area. Then you will have to add a flat surface to the bottom of the Sweptline's frame from the rad support to the end of the rear spring hanger to get rid of the Mopar hump in the font frame rails so the CV suspension has something to "bolt" to. That flat surface will have to be long enough to pick up the back end of the lower control arm mounting as well, hopefully they are close enough inline with the other mounting holes.

The CV has something like 4" of backspacing on the wheels, you did get the wheels as well, right?

Take pictures of your progress. It would be nice to have a documented step by step procedure of another option for a front clip, as limited as it might be. Gene
