Got the passenger side sealed up. Still have a little more arch to finish. Fiberglass and rubber undercoating to patch the hole. Seems pretty tough. Drilling the holes for the bracket was tough was the hardest part. Overall the stock mount was still solid but didn't want to worry about it again. New brake line while I was there and had to patch where the cut off wheel got to close. The drivers side is on hold till I fix the Focus.. again. That side hasn't rusted through yet.
