I finally finished my external roll cage. I also recently made a skid plate for the transfer case/cat/etc... The skid plate was a lot easier to make (i.e., clearance issues) than I thought it would be.
They are definitely negative, but they are the front springs. I only have about 1 inch between the axle and the bump stop! I guess a couple hundred extra pounds of cage and winch doesn't help. Resolving my spring problems is my next project.
