I have a 2013 Chevy 2500 6.0 ext cab long bed. Frame is rotted. I’ve been searching everywhere for one without luck. I found one. For an 08. I’ve done some research and the only thing I can find is some thoughts about the rad support. I know the frame part numbers are different and I know the spare tire mount is different. Question is can I still use it on my 13 though?
