Bill and Tim,
This is getting repetitive (as far as THANK YOU goes) I will THANK YOU both again! I hope the other readers are following, that the main topic is still in play, as by determining the original paint color on the truck (with the Door Data Plate numbers) and cross referancing with the years that color was available will, more closely if not exactly, determine the year of the cab!
My wanting to know if (Shades of gray) were available in that year is simply in keeping true to colors of the time. Though not authenic to the truck, time period correct. Maybe also imagining, if I bought the truck new, the color(s) I would of picked!
I have learned more in the last 2 or 3 days of determining factors, numbers, and options of this truck than I have knew or found out about in the 2 years I have owned the truck! Very valueable information, my hats off to the both of you for your responces!
Again, Thank you again,
