Wade,

 I do not have any photos of the process, however, it is fairly simple.  If
you take the thermostat housing off the water pump and look inside, you will
see directly below where the thermostat sits a hole in the pump housing wall
approx 1/2" in diameter.  You can't miss it, its the only 1/2" hole there.
Its the right size to take either a 1/2" or 5/8" NPT tap (I am almost
certain it is 1/2").  You can get bronze plugs for that size from you local
hardward store (used to plug gas pipes) or aluminum plugs (recommened) from
the places that sells AN type fittings.

Its been six years and memory is a bit fuzzy, but I am fairly certain that I
did not have to drill out or enlarge the hole.  Just find a socket that the
square end of the tap will fit into snuggly and put it on the end of a 3-6"
extention.  Then carefully insert the end of the tap into the hole and begin
to turn it CCW. Try to maintain a perpendicular position at all times.   The
tap will catch and slowly cut its way into the hole leaving you with threads
for your plug.  Stuff cotton or something to catch the metal chips and then
flush from the other side of the water pump.

Be very careful not to exert side force on the tap.  They are fairly brittle
and won't take much side force.
