I'll take the "brain going at a 1000mph...with no real objective" as a compliment of sorts...since I tend to take an optimistic, cheerful view of such poorly-selected words.
Let me reassure you, I have no intention of this being a futile exercise in intellectualisation. On the contrary, I view this as a preparatory stage for the coming rebuild. A time to conceive, plan, and strategize the essential elements of WHAT to do, WHEN to do it, WHERE to do it, and HOW to do it. I'm in absolutely no hurry to start this build at all, since I'm already building an '84 FJ40 (for the last year) a '65 Chevy Impala (for the last 8 months) and a '67 Chevy Impala (for the past 6 months). So please...let me hasten to reiterate...the seemingly directionless ramblings in this thread are NOT total randomness on my part. On the contrary, all of this is a very deliberate, very precise process of whittling things down to the very basic requirements. If it appears to be complete chaos...well, let's just say THAT is by design, and not by default.
Thanks for the offer of help. It's much appreciated.
