Whats up with the stock body parts of our Z's? Are they interchangeable?

i would like to put the black lip, and sideskirts found on turbos, on my NA...

Do i need to replace the whole front bumper? or does the lip just fit on?

For the sideskirts are they any modifications that need to be done?

Thanks guyz

'84-'86 parts are a match...
'87-'89 " " " "

You'll have to play with the lip (sounds perverted), but the side skirt are just fit, drill, and screw

 

just remember the fenders are slightly different on the 86 model year.
