That is what people will say, "Why in the world do you need that". Who cares!!
I'm getting mine setup now to carry my rockcrawler to and from events. Also, I've got a Sprauge type transfer case in my truck now which I'll be switching out to an Airshift unit soon. The airshift is in the back of my Toyota pickup; I've just got to make a lift so I can get the old case out of the truck and the new one in. Anyway, if you need Sprauge transfer case parts for some reason I'll be happy to more or less give you the Sprauge that's going to come out of my truck.
Just shoot me a PM if you need anything or have questions, Ross
