I did do a search. What I did find out was that there were a few different style that had different dimensions for the rear seal but I didn't find enough to identify which was which. I appreciate you replying back because I have seen tons of your posts and you are one that seems like you know a great deal about these engines.

I believe it was the 6.0 crank that had the different rear seal area (longer i think? not sure..) , possibly because of the 4l80e tranny it mated to?
Truck cranks are also not gun drilled like ls1 cranks which makes them heavier but not necessarily stronger. It should be fine but id wait for someone with a definite answer before i committed to buying anything.
