ummmmm. never said they were just alike, I was just telling everybody what I had. and yep. its a 2x3 main frame rail car with a 4 link, and I did jack mine up as far as it would jack up.and it flexed the 4 LINK bars and never lifted the pass wheel. heck I even had the drivers side rear wheel also most off the ground. and the pass side was buried in the wheel well. no frame flex just 4 link movement, I Really think you need rear end set up tighter,
