I will be degreasing the wheel wells next and I needed to close up some holes into the frunk, so I put some metal tape inside and outside a battery acid burn through hole:
and installed some screws through roofing washers (metal washer with neoprene washer on one side) in some screw holes that used to support hose clamps that I will not be using:
I then made some horn extenders as I will be mounting one horn per side behind the horn grills. The original horn wires go from driver's side to passenger's side where the both horns are mounted in front of the oil cooler pointing down. There the wire jumpers from one horn to the other as they are colocated there. I just made jumpers from the one horn and ran them back to the other side of the car using some 14ga wire.
