Actually figured out the difference between GMT -800 &-900 I am wondering if I can take everything from my 08 and bolt it to the 11 frame. The rad support, bumper, cab and box

But the body panels (cab, fenders, box) are all the same from 2008 to 2012 are the same are they not? What does the GMT-800 and GMT-900 mean?

I assume they are different frames as one is a fully boxed frame (2011) and the other is a c channeled frame (2008)

Hopefully someone can help. I am in the process in doing my 2008 GMC Sierra Crew Cab 2500 HD over. I was wanting to change the frame over and I found a frame from a 2011 GMC Sierra 2500 HD. I am curious if they will interchange. I know the body panels look to be the same, but I was told the rad support is different between 2008-2011. I know the front bumper is different too but I wonder if they still mount the same. I am assuming my LMM motor and transmission will just bolt in will it not? I would like to have the 2011 front bumper and the hood but still on the look for it but if I need to, will my 2008 Rad Support bolt to the 2011 Frame? I did do research and it looks like if I was to use the 2011 Rad Support the 2008 rad, Intercooler, Condenser are different. I do know there is a difference in the frames between 2008 and 2011. The 2011 frame is a boxed frame and the 2008 frame is C- Channel. I am told the 2011 frame is a better frame thou. Thank you ahead of time for the help Chris
