Relocated leaf springs '69 Dart - Which shocks are correct?

I always measure the distance between the upper and lower shock mount then you have two choices. Go online to the monroe shock website and you should be able to find a chart with just about every shock ever made. You find a shock that has a collapsed and extended length so that your measurement falls in the middle. In other words when the shock is installed it should be able to travel equally in both directions before hitting the end of the travel.
Or, take your measurement to O'Riellys and they can also took it up in one of their old shock books. It should also have the different collapsed and extended lengths.
