frame dimensions?

[justin51986]

I don't know if this is the right section to ask this in, but here goes. I just acquired a 1970 mach 1, and pretty much all that is left is the shell, no floors, no rear frame rails and I think I want to build a full chassis for it. i am a good fabricator, but I am still learning the suspension design basics. I think I can do it, and the best way for me to learn is to just start doing it. My question is, is there anywhere, or has anyone done a write up on building chassis'? i have used the search tool, but still can't find what i'm looking for, any help will be greatly appreciated!
