thanks to @TFaoro   Here I'm going to try to go through everything I did to put an he351cw off of a 2005 CR Cummins onto my 2002 24valve Cummins.   There may be some redundant pictures in here, so bear with me! I started by buying the parts I knew I would need. 2 turbo mounting studs from Cummins (I bought the stock length for an 05) These screwed into the bottom of the manifold. The other two were plenty long. 2 longer oil return tube mounting bolts 2 90d
