1973 ac brackets

[chuckdel]

anyone know if the 400 ac brackets and pump from a 1974 roadrunner will fit the 440 I am having issues with the brackets fitting just right the way it was bolted to the 400 and looks to be setting back one inch to far. I am thinking that the water pump housing may not be the same?

The A/C brackets and pulleys changed in 74 from 73 as well as the water pump housing. Also some of the brackets are different between 400 and 440 due to the 440 being a tall block.
