The combination of an SMB 4x4 conversion with a 7.3L diesel is very rare. SMB had just developed their own 4x4 conversion right around the time Ford was changing over to the 6.0L diesel was so there wasn't much overlap.
It's the holy grail because many people prefer the SMB 4x4 system to other 4x4 conversions and many/most people prefer the 7.3L diesel over the 6.0L diesel.
SMB-less as of 02/04/2012. Our savings account is richer, but our adventures are poorer.
