Byron,
Yes, I do have a diff lock on my van - but it has 14" wheels.  I have seen
pictures of the non-locking front diff in the Bently manual which seem to show
the feature on the housing casting  where the lock fits.  If that is the case it
may be possible to machine a hole in the housing for the lock assembly, drill
and tap two holes M6 for the servo bracket and then fit the locking bits and
pieces.  The principle of operation of the front lock is the same as the rear -
I dont know if the internals are the same but if you are really serious I could
try to compare the part numbers sometime.  I think it might be easier to obtain
a used front diff from Europe!
