switching to aluminum high flow waterpump, questions...

I bought the bracket set from CVF Racing when I made the swap , however it only works with a specific Saginaw PS pump and it had a slight belt rub from the PS belt on the water pump pulley which I just fixed after 3 years by buying their billet pulleys for the crank and water pump -check their site for more info .
Bottom line when I made the swap none of the pulleys from my 69 319 would line up with the 70 up water pump you are switching to .
