So a couple years ago when I started rushing into a project I welded in these P&J ladder bars on the rear. Flash forward to today and I am getting back to this project. While figuring out my sub rails on the frame I noticed that the rear of my ladder bars are higher than frame level by about a half inch. The rear angle is correct. That being said, can I get away with leaving them like this? I plan on using the original subrails with wood blocks. That will clear the ladder bars but I'm not sure how much they will move up and down.
