i have a 86 z28 and need to replace some of the ground ground effect pieces. i know that the early 80's are different but not sure what year they changed , 85 / 86 ? then what year did they change again 91 -92 ? basically i'm asking what year range will fit a 86 z28 ? any info would be apprieciated thanks

 

They were changed again in 1991. You should be able to fit the ground effects from the mid to late 80s models.

 

The year breaks are, 82-84, 85-90, 91-92.

 

thanks !! thats what i needed to know.
