BODY DIMENSIONS V The front suspension is a MacPherson strut style. Adjustment of the front wheel alignment is limited to camber adjustment. The front wheel alignment is determined by accuracy of the body itself. Accurate measurement and dimensional accuracy based upon the body dimensions are required when repairs are made. EXPLANATION OF BODY DIMENSIONS PROJECTED DIMENSIONS Flat-plane dimensions are those dimensions as measured on a flat surface projected from certain designated standard points of the body. STRAIGHT-LINE DIMENSIONS (ACTUAL DIMENSIONS) w Actual dimensions are those dimensions actually measured in a straight line between two points. Note Before the work, adjust the body according to the standard measurements and check the fit with associating parts, then proceed with the work.
