If you deloom the wiring for the tb you can get enough slack not to extend the wires. Same thing for the alt wiring. I have no Idea what your talking about with the alt and using a manifold bolt though. I dropped mine using the oem hardware. Did you slot the cover for the alt so the a/c belt doesnt rub on it?
Btw, Id ditch the red grounding wires, they make the engine look cluttered and do nothing.
You could clean up your vaccum lines by filling the upper ones and retapping them in places you cant see.
What fuel lines are those they are wayyy too long. A hydraulic shop could shorten them for you.
just some constructive criticisim.
