Right and left motor mounts difference

[AmadeusCharger500]

I'm putting a 74 charger back together. The engine's (400cid) left mount originally had a bottom bolt missing and there was a chain attaching the mount to the k-frame. Now that the engine is being dropped back in (with newly restored and painted mounts, carefully marked left and right) The engine won't sit in the perches. I'm noticing the left and right mounts looks suspiciously the same! The left mount appears to be pulling the engine foward toward the k-frame causing the oilpan to hit the frame and not allow engine to settle.
Anyone have pics of what these mounts should look like?
