I've done abit of wiring myself , mostly racecars too. I'm ok at it but not great you can tell when someone is really good things just look right!!.
Any way just the other day my father had problems with his 55 chevy ,he could't get it going,I looked under the dash and could't believe the mess BAD!!
I could do it but dont really have the time or desire , so if you book some jobs out in the east let me know how much it might cost.
good luck
