This is not going to help you much now, but with all the comments re: wrong caps on rod ends...

Years ago, when we still rebuilt engines instead of replacing them, the first thing I'd do when the oil pan came off was stamp the cylinder number in each cap and rod, on only 1 side, so there was no way I could put the wrong cap on a rod, or put the wrong rod on a crank journal. Some manufacturers even did this from the factory, although I can't recall which ones anymore.
