What is the difference between GMT800 upper control arms and GMT400? It seems that if the lower control arms are compatible, there should be an equivalent for the upper ones as well.

i was gonna go this route on my 99, but started tearing it apart and found entirely too many moving parts. So this weekend I'm getting the stuff to SAS it. If you get the right knuckles only have to ream the top b/j. I think the upper arms having different mount locations. I forgot that I have a set of the lite duty 2500 knuckles....
