Looking for correct identification of a 68 roadrunner 383 power steering pump...... It seems that I have narrowed it down that it should be a federal pump but there seems to be two different versions..... Looking for people to chime in who may have an original 68 roadrunner or GTX with power steering...... Pictures attached...... One has approximate 5-in pulley solid in the other version has a 7-in pulley solid each pump has different mounting brackets.....
