I figured I should post this picture of my Raleigh. Since alot of the parts are proberly close to the same. mine also had the same bag on it lol also post close up pics of the things your wondering about. on my light theres a pin under it that has to be released then pushed. but the light was stuck because of how old it was so I had to pry it.

Fenders? find another Raleigh. alot of them have same fenders beside braces. but you can alter to fit your braces if ya wanted.
