Pre-Runners 73- 87 Any pics

[C-10 simplex]

1) Please define "pre-runner."

2) Can you recommend any good websites/magazines/races(i live on the east coast so it may not be feasible) that can illustrate what i need----i need ideas on how to mount the fenders and hood so as to make them quick-release so as to fascilitate easy engine access.

3) Does anyone know of any companies that sell bolt-in roll bars/ cages for the 73-87 series trucks? Yes, i know bolt in is not as good as weld in, but i'll explain later......
