I have a 2011 Ram 1500 SLT 4x4 quad cab . I have some front end damage from accident, bumper, hood, grille, etc. I really love the new 2013 ram sport front bumper, grille, vertical driving lights, projector headlamps. I know the headlamps will fit on truck, and work with harness adapter. I have been to a couple Dodge Dealer Parts Departments, and searched the internet. I can not find any answer as to if the 2013 front bumper, and grille will fit on 2009-2012 model. If I buy the parts they can not be returned if they don't fit. I know there may be some different mounting brackets, and the impact absorber is different. But I dont know if the bolt holes on frame horn, and radiator support from 2011 model would work on 2013 model grille, front bumper. I would just like to know if anyone has done this conversion, or have any information on if these parts will work, or will not work without major modifications, cutting, drilling,etc. I am new member, but longtime reader and fan of this forum. Sorry for the lengthy question, any help would be greatly appreciated.
