I did a search and saw several discussions, but no images - Anyone got any good pictures of the frame mounted rock rails? - Pics of them on a 4-door would be nice as that's what I've got.

I'm trying to figure out how they mount under there - didn't see anything to attach to. I'm guessing that you've got to drill holes for the installation? Do they bolt all the way through the frame? (what about the fuel tank area??)

 

look for Eddie's write up on the shrockworks rails, he did the write up on the project-jk.com website
