i asked the exat same thing when i got mine in. in hand they look a lot alike. once you go to put them in, and i would advise putting them in with the engine, they will line up. the holes closeer together are down. they swap side to side so no worries there.
if the engine is out now just remoce the frame mounts and line the holes up. if not, like i said before, the holes closer together, by a smidgen, are down.
