73 360 in 66 Cuda Water Pump

I have a 1966 Barracuda. I put in a 1973 Plymouth Fury 360/727 and used all of the 273 externals - water pump (iron), alternator, distributor and exhaust. The flex fan is just over an inch away from the 67 radiator that I had triple cored. If I used the 360 water pump the fan would be in or in front of the radiator. I still have the 66 radiator because this was a weekend swop so I had another radiator done before hand. I later took the Fury wiring and upgraded to electronic ignition, voltage regulator, dual field Alternator. PS & PB. Eddy intake and 4V......

If the Milodon info is correct and the difference is 13/16", it would seem that a shorter fan spacer and possibly a different pulley would allow the 73 water pump. That and a right side outlet radiator.
