So, I've gone ahead and called ILT this morning.
They had the divider plates as was mentioned earlier.
The part number for 69-77 model year is : INL11103 $11.00
Part number for 67 model year is: INL12846 $39.00
Shipping from MI to KY was over $12!
Total cost was $51.40!! (Seems a little steep considering the water pumps are probably cheaper but, I am deferring to the experts here and if this can save me the aggravation of fooling with a car that overheats, I guess it's worth the dough).
Once I can source a water pump I can post pics for all to enjoy!
