Hi Mac,
I'm on the plane right now so no pics, but my drivers side fender has holes for the horn directly across from the center of the exhaust manifold, so pretty much dead center in the fender. �There is a support on the under side that gives the horn the support it needs to not flex the fender wall. �
I also have a set of holes at the front about 4 inches back from the grill where the headlight Block mounts. �Its not a fuse block, it has the connections for the wiring harness in the grill to wire to the harness from the dash. �I've got a couple of other holes between the horn and the firewall, I use these to secure the headlight wiring harness with some wire straps. �Hope that helps.
Also the footman loop on the windshield is on the inside of the windshield, but mine is welded in place not bolted, so there are no penetrations to the front side.
