Before you take your fender off you may want to close your hood and take note of your body gaps.
Also measure your firewall brace rod before you remove it. If your 1ton ND has them ,I’m working on a 50 AD 1/2ton
Take lots of pic’s so you can refer to them at reassembly.
Two years ago I removed my lower splash apron t paint it, next thing I knew I had the whole truck apart.
Good luck.
