Springs are fine, M-18183-C mounts are for 2005-2010 cars or all 07-13 GT 500s. You can reuse stock paper strut mounts or if changing struts buy ones for the earlier years. I believe the Ford Racing struts are the earlier year shaft size which is larger diameter. Rick, Gary and others know this better, I run Koni Yellows and the C mount upper isolator with P springs and Maximum Motorsports camber plates.four-walling said:Reply #125 in this thread has me wondering-
Will the M-5300-P springs and M-18183-C strut mounts not work with the factory struts?
