Glen, A flash distributor is used for the old 4P analog TTL flash stuff (AF280T, AF400T). For your PZ-1p & 645n all you need is a Hot Shoe Adapter F for each flash (they both go on top of each other in the hot shoe) and then a 5P or 5PL cord that goes from the Adapter F to the flash. You can do contrast control by setting one of the flashes to that mode.
However, that being said, JCO has given the best advice - run them manual instead of TTL and use a flash meter so that you can set the proper ratios.
