Yes, when building from scratch, it gets rather interesting---The fiberglass fenders don't have any holes to align them, and the aftermarket fender braces have so much slop at the bolt holes that they will swing almost 2" to either side of "center". I was fortunate that I used an original A frame, because at least that let me correctly position the aftermarket fender braces where they attach to the frame, in the holes that were for the original fender braces. Odds are pretty damn slim that things will come close to lining up now when I go to install a set of original fender braces.
