1971 340 water pump and crank pulley problem

hey guys,
got a 69 dart. 71 motor. no power steering, no AC. the water pump and crank pulleys arent lined up so it has two belts. i replaced the alternator bracket with a oem replacement. now the belts are too tight. though im no master mechanic, ever since i bought this car ive had to fix some things the previous guy did. whats my best solution? new belts or replacement pulleys. thanks for any info guys.
