I did a couple quick searches but did not come up with what I was looking for. I just took a 2001 7.3 superduty on trade for a truck I had. The superduty the body has pretty much rotted off of it and I know where I can get a super clean southern rolling chassis CCLB obs that had a 7.3 in it a guy bought for a cummins swap and never did. I could probably get the whole truck cheaper than just a box for the superduty. But how much of the drivetrain will go in the obs and would it be a huge headache? The 7.3 I have only has 100k and runs super strong so it appears to be a good drive train. The obs has no motor but I am not sure about any of the accessories like brackets up pipes etc.
