I am building a 1970 , 440 Challenger . While getting ready to set the motor in this up coming week end I have noticed the 2 mounts are different . One has what looks like a pipe welded in on the engine side and 1 dose not . Next which mount is on which side will move the motor forward or back about a inch . Dose anyone know if the side with the pipie is on the drivers side or the pass . Wish I could post pitchers but I do not know how and I have tried . Any help will be appreicated . I really want to put the motor in Saturday .
