Hopefully getting plenty of views !! 
I took of my wheels this weekend to get a look at the brakes. I knew they needed to be replaced, but wanted to check everything out myself. One wheel had one lung nut and the other had a different lug nut. IIRC one was 3/4" and one was 13/16". You can also see the different style. When I do the brakes, I'd like to get the right lug nuts on the whole truck. What should I be using? For reference, I have the 15" steel 40-style wheels.
Thanks in advance for recommendations.
