At the top of each piledriver you should see a set of "grills" or "vents" -- those are the back end of the piledriver. This picture shows Rumble's piledrivers attached backwards - so you can see those "grill/vents" toward the top of each. When attached correctly it should look like this (vent/grills not visible from the front).
Also the insides of the piledrivers are asymmetrical with the bit that holds onto the guns facing toward the rear.
