is a arm diffrent
 

is there a diffrent a arm on a iroc z with the heavy duty suspension and a 88 sc with a 6 cylinder thanks for any help

i don't think there is but i will tell you from experience that the v8 and v6 cars use a different bearing mount for the front struts. i bought some used drag struts for my former v6 car and found out the hard way that v8 cars use a longer bearing mount
