I ditched my liners when I chopped my fenders. I tried to mod/cut them to fit back in, but just ended up ruining the drivers side one...and gave up.
To me it seems a little dangerous b/c there are some exposed little connectors and wires what not. Some stuff look like it could possibly get snagged on a low bush or something if you got into something hairy. Also mud and water get all up in there. Further it just doesn't look clean.
You can order liners from Mopar, but you'll have to cut them too. These from MC look perfect for what I am talking about. Sounds like two extra drill holes and some blots and they will go right in. Thanks for the post, I'll def pick some of these up for $180.
