My current tailgate is rusted to crap and has cracks... its also REALLY REALLY heavy! anyone know why its so much heavier? Its a manual window, would that make a diff? Anywway, If i bought a repro tailgate from LMC, would it fit pretty well? And what is diff between OE and repro? And its just the shell right? So i just throw in all hardware and glass from other tailgate into this one? Is that pretty easy? Thanks!
