I'm pretty much on board with Almostdone's post regarding "period flavor" I like a rod to look the part, but I'm not opposed to using better pieces as long as they don't destroy the look. For instance my '56 Chevy is supposed to look like early '70s because that is when Dad built the car the first time. However, I'm using Pertronix ignition and a one wire alternator. Also, something I thought about a lot: Does period correct mean Common during the period OR Available during the period? I wrestled with things like that concerning things like front discs or fancy heads. It helps to set my mind at ease a bit when I look at some of the crazy stuff on race cars of the late '50s and '60s... Like the front discs on Ohio George's Willys.
