HEY GUYS, IM CONVERTING A 340 71 CHALLENGER TO POWER STEERING. I HAVE A SAGINAW PUMP, SAGINAW BRACKETS, AND PURCHASED THE 2 PULLEYS AT THE MOPAR NATS. AFTER BOLTING ALL IN, THE PUMP IS 3/4 OF AN INCH FORWARD MORE THAN THE CRANK PULLEY. THE CRANK PULLEY MEASURES 3 1/4 INCHES DEEP. CLASSIC INDUSTRIES MEASURED THEIR PULLEY FOR MY APPLICATION AND IT WAS 3 1/4 INCHES SO THE PULLEYS I HAVE ARE CORRECT. WHY IS THIS NOT BOLTING UP? ANY HELP WOULD BE APPRECIATED.
