I've only had a spare R fender for ~5 years, and it's almost the right color.
The top L 2 bolts that go to the cowl horn are 13mm, as is the one for the hood support & the bottom L.
The lower L bolt (near the lower door hinge) is 10mm like the one in the middle of the wheelwell arch, and the 2 for the core support corner (with the hood bumpstop).
The small screws around the wheelwell lip are 5.5mm.
The bolts from the core support to the fender & from the fender to the grille valance are 8mm, as are those from the wheelwell to the core support below the battery.
The ground stud is 11mm; the starter relay screws are 8mm. The battery tray bolts are 10mm, and its support arm uses an 8mm lag screw.
