Us7 - the facing of the bolts doesn't really matter for a ladder. The thing you want to avoid is not having enough room to conveniently get a wrench on the bolt to remove or install it (some rails have the 2 ends ~6" from each other and loosening or tightening the bolt is a real pain because you can only get partial turns on them). Otherwise the positioning of the bolts doesn't come into play, as long as you have escution plates it's not a matter of aesthetics.
