I removed my headlight buckets with the fender on the car, yes the forward splash sheilds need to come out. It then takes a Looong extension to reach the top hood side corner nut. Make sure you're fully engaged on the nut so you don't strip any. I blasted water in there first as dirt will keep the socket from seating. I think I used my 1/4" set of sockets to have more room. You can get your hand in there to find the location of the nut but hard to do with the socket at the same time. I can post a pic of the inside of the bucket when I get home in a couple hours so you can see what your looking for and how many total. I think it'll be easier on the car so the fenders not rolling or shifting while you're trying to unscrew.
