I re-routed the parking brake cable from above the frame crossmember to below the frame crossmember on my 392. It has a Metalcloak 4.5" lift and King shocks for a 6" lift, so there is a lot of suspension droop, and the cables were too tight at full droop.
Then I went out to the 3-Peaks OHV Park 10 miles from where I live to check the suspension at full flex. There are two large threaded embossed mounts on each side of the top of the rear differential on a 392 that I was concerned might snag the emergency brake lines after they were lowered.
Good news: no interference was found. And the new 40" + inner fender panels from Next Venture made it so there is no tire contact. The cutting of the body tub was worth it.
Zoom in and you can see the two threaded protuberances on the top of the differential. The emergency brake line lies right between them at full flex.
