thanks, I'm still trying to figure out if I'm going to have room to run duals out the back with an X-pipe or if I'll just have room for one to go out the passenger side. I acquired a 4wd ZF5 for it because it was cheap but I'm going to pull a 2wd which is what I really wanted in the first place this weekend so that will help immensely with this project. May be looking at a move in the next few months so won't be doing the swap until the move unfortunately. I need the truck to be driveable to get on and off of the trailer and in/out of the garage etc. Should be a good drivetrain when I'm done.
