Posting for a friend he is wanting to put itr side skirts on a civic, Integra side skirts are smaller then civic wondering how this can be done .
Here is a picture of what hes wanting to do

 

You would only need to cut them apart and extend them using standard fiberglass/plastic repair processes followed by standard body work and paint. Make sure tabs/holes/mounts line up and you're goo to go. If they don't line up you just create what you need.

 

mk thank you for the help
