I am installing a 440 into a 65 Dodge Coronet.The car was originally a 273 with power steering.My first question is can I use the power steering pump from the 273? The 440 is from a 1977 truck.The water pump is a Mopar P4286899.The power steering pump bracket from the 273 won't adapt to this pump without modification.I will also need both pulleys and an alternator and bracket.Where do I start and where will I find the right parts?
