Newbie Questions

[55454]

I re-titled this post for more input, the newbie title didn't draw much attention.



I have been watching this board for over five years, and have had one or more 68-72 tagged titled and insured since 1981 (never owned a 67). I am currently building a truck and would like to ask some questions, some may not seem relevent but I have over twenty years of parts and need to structure a plan before resto begins. I want to make sure the two trucks I have are original.
