68-71 arm rest size/spot?

[muddpile]

Well, my interior goes for upholstery this week, and it just occured to me that I need to know how big the 68-71 arm rest is for my custom door panels. Here's a picture of the measurements I need:



That way I can draw it out on the wood and design a custom door panel of some sort on the flat wood that I have. Also, what colors do those come in nowadays as replacements? I want parchment, or off white, and was wondering if anyone sells that color in the old style arm rests. I have 72 style right now, and like that color, but want the earlier style. Thanks!
