Converting from cast iron to aluminum water pump

And a few more questions.....what balancer are you using and where are the timing marks on it? Still the later timing cover and timing gauge? Early cover with bolt on (or cast in) passenger side timing gauge? All brackets and pulleys will be different between the two setups. The bypass hose between the water pump and intake is a different diameter too, so, either change the intake fitting, or, make some sort of conversion connection. Fan spacer is probably going to be the wrong length too.
