1965 c10 short wide rebuild

[bigblok77]

hey guys, new to this forum, going to post my build on my c10, first of all, it is all origina metal, almost zero dents/rust (just surface) the bed has a few more dent than anticipated, but I will deal with that later. As for now I want to put a motor and tranny in it, (probably 250 6cyl) because that is in my garage and it runs.. lol as of now I am working on the surface rust problem, it is pretty deep pitted, and I am led to believe that the rust kutter I have will kill the rust in the pits that I cant clean up with a wire wheel or hand brush, and the I will spray a good epoxy primer over that. please advise if I am doing this wrong.
thanks!
