Just saying Hi; new truck owner.

As of today I bought a 1967 Chevy C/10 Stepside for the large amount of 200 dollars. It has a straight 6, manual everything, and 3 spd converted to floor shift. Has a few questions to start;

1. Can I use a late 70's HEI 6cyl distributer in this engine? If so what else do I have to change?

2. Is it legal to turn the exhaust out to before the rear wheels? It leaks right around the axle and i dont want to have a whole exhaust put on.

3. What the heck is my shift pattern? It didnt seem to care what gear I started in, but I cant tell which gear is first.

4. What are some catalogs that I should order (must be free)

Thanks, I'll post a picture soon
