Thanks! Looks like I’ve got most of the wiring harness done. I still need to address the battery and starter wires. Don't think I want to spend $200 for a repro set which is hit or miss on correctness anyway.
I've been trying to find a heat insulator gasket for the 1406 to raise up the butterflies a little so they don't interfere with the intake but no luck yet.
Pretty close to trying to fire her up for the first time in at least 30 years!
