Ideally your rack should be level, and attach to the front fender.
From my friends at Norther Cycle:
The backstop (or "tombstone") is where you slide your handlebar bag over, and is typically the same angle as your head tube (~73 degrees) from horizontal.
The problem is that
none of the off-the-shelf bikes fit on any bikes to make the above happen. When you see those two conditions met, it's almost always a custom rack. I've modified VO racks a few times by cutting off the centerbolt portion and rebrazing a new piece in, but it still required some long spacers to connect to the fender.
On the other hand, it's not a big deal using it just like you have it.
Re: daruma bolts-Yeah, not a great fan. A better alternative is to have a bit brazed onto the fork crown to directly attach the fender by feeding a bolt from under the fender.
OCD? I think you're right, most of us are here to some degree or another! Especially those of us with several bikes, when you can only ride one at a time!
