I've heard that the Jeeps also had a Levi's option, and brown was one color, blue another. THey may have used a different shade for the Jeeps versus the cars. Ig, though, it's possible there were different shades that are "correct". If you actually FOUND something close, I'd go ahead and use it! The Levi's material in my '78 Gremlin GT is blue, faded to light, but the part I peeled back on some door pockets is much darker. So, not sure what to tell ya. The Jeep stuff is probably rare enough, might be worth buying the whole roll! Jerry
