Just a couriosity question. Is it possible that A-Body 383 vs B-E body 383 route wires different?
As for accuracy of repo parts I just replaced my fuel lines from pump to carb on my 273 2bbl and the Classic repos were close but the curve at the fuel pump is significantly larger then oe.
I also replaced positive battery harness, same thing, a few inches shorter, and the molded section at the firewall at the hold down clamp was not as long as oe.
