Sorry, Phil, but you're wrong ... the original size and spacing of the teeth
on the water pump sprocket can be seen by looking at the unworn edge of the
sprocket and it clearly matches the timing belt.  In addition, I have verified
(by looking at the parts invoice as well as physical inspection of the parts
themselves) that everything I used -- cam sprocket, crank sprocket, idler
pulley, water pump and timing belt -- were indeed the correct early-style
parts and properly matched to each other.

I hate to admit it but the bottom-line is obviously that I screwed up when
installing everything and now have to do it over again prematurely as a
result.  Live and learn...  :^(
