73' B3 340 Duster pro touring build

I like the look, but man that tire looks so close to the front of the fender. I am sure it is the way the picture looks maybe your neighbor moved it forward when you were not looking. lol

Question for you, Not being a body filler person, having never done it, do you have to sand the primer down to metal or can you fill over the primer? I know dumb question but hey gotta ask.
