I read this on the other sight and have done a couple trucks now. About a 15 minute job and you need a small grinder is it.
You pop off outside the rail cover for the seat you want to do.
You will see the screw that adjusts the seat angle and a small collar on the screw that limits travel. (arrow)
You just grind the collar off trying not to damage the threaded rod. You don't need to cut it all the way through, just enough to pry it off.
Once removed just vacuum and put the cover back on and you have fully reclining seats!!!
