I changed my lenses over the weekend, and I think in the process I must have caused them to become unaligned. I removed the headlight assembly to get the lenses on, and I think I must've nudged, and therefore accidentally adjusted the knobs. I thought I thought I put them back in their original positions, but it seems that they're both a little low.

I've tried looking for some threads about it, but seem to run into threads about later models.

I know where the adjustment knobs are, but I'm wondering what specifications do I use to make them correct?

As in, "at 20 feet, the center line of the drivers side headlight should be X inches above the ground, and the passenger side headlight should be Y inches above the ground".

Is there such a specification?
