No...we were discussing your 1500 running gear. You'll need lots of beef for those 37's and not just the axles, er differentials to start. You may discover that as you go along, or spend the big bucks from the start and do it right so you don't have to do it over.
I would look for 2002 2500 or 3500 diffs. 35 spline front axles and no front cad unit. Earlier units have weaker 31 spline front axles (same as your 1500). Then a H.D track bar. Steering would be '06.5 hd or some kind of heim joint setup. Then a steering brace to limp your stock box along.
I reread your original post and noticed you want to install a "3 inch leveling kit" This will relocate your axle back towards your cab and unncenter it under the frame about an inch, further reducing clearance. I would recommend a proper 3 inch lift with longer arms, or a 5 inch lift with your BL.
