What's the correct taper for the hood stripes?

[dboles]

My '69 Z clone is going to the body shop in a couple of days. I'm changing the blue stripes(on it now) to black. I've recently read that the stripes have a taper to them. Is the taper only on the front or also on the rear stripes. How much of a taper is there? And where is it measured from. Are the rear stripes tapered?
