Steve -- I think you should ask Ed some more questions about his 302 he's offering you ... Do you still have access to your friend's garage? And be advised that you seem to want to do to your truck is not a simple weekend project and will most likely put you in violation of your HOA/Lease *especially* if you pursue an unusual configuration (then Bart's suggestion of the mocking up process is the only way you will succeed).
Just sayin' ... 'cause there might be a slight disconnect between what you want to hear and what you need to hear. Take what these guys are trying to tell you to heart. They truly are trying to help.
We're here for you, regardless.
