hello, sorry i was gone so long. i,m building a house and got a new baby 3 weeks ago, so you can imagine how busy i,ve been. i think you could probably do one without a body lift. you would definetly have to do some "hammer molding" to the floor pan and even then the whole top of the trans. is going to set against the floor pan. i had allready put a body lift on my truck several years ago for other reasons, but i'm glad i had it because it made this swap alot easier. the floor pan hitting is really the least of your worries. it would hit the bottom of the 4x4 shifter and it would also be in the way of the linkage. also with no body lift the trans. to engine bolts on top would be almost impossible to get to. i'm going to put together another complete kit for this swap and try to do an article in TDR with alot of pictures. i'm going to do it on a truck without a body lift. i'm sure it can be done it's just alot more work. i didn't think a body lift was such a big deal, i've had one on the last 4 dodge cummins i've owned. they are cheap, easy to put on and makes working on anything under the truck alot easier with the body not setting right on top of everything. on anything else i think they look retarded, but you can't even tell on a dodge. iv'e always gone with a 2". anyway it may be a while before i can do an article with everything else i have to do right know, but i will.
