This company makes a matching color of Santa Fe Tan paint (same as 77 Kingsley). If your looking to match your paint color the paint codes for 73-75 can be found at http://www.gmcmotorhome.com:80/faq/GMCExterior1.html and for 76-78 at http://www.gmcmotorhome.com/faq/GMCExterior2.html . You may even be able to buy spray cans of your color from here http://www.ppgcarpaint.com/ or here http://www.carpaintonline.com/ I want to thank Rick Denny for his persistence at uncovering this information. Emery Stora adds \"there is also information on pages 1-4 and 1-5 in the Maintenance Manual X7525 \". Also Paul Bartz adds some information about a 78 Royale "the correct
number is Krylon 1503 Antique White, which you can find at a True Value Hardware store. It's the same color as that referred to on the top table, p. 1A-2, in the X-7725 (1977 & 1978 Supplement) shop manual as 38P Frost Beige for the Transmode model. The DuPont number is 45554U". Emery Stora follows up by stating that he has been recommending Krylon 1503 Antique White as an excellent match for the 77 Kingsley color. Also someone has submitted that Navajo White sold by Ace Hardware premium enamel Navajo White, P/N 17185, bar code number 82901 17185. So it appears (?) that Santa Fe Tan, Antique White and Navajo White are all the same color. Rick Denney has additionally posted information about Glacier Sky Blue "Go to www.PPGCarPaint.com, and order the Fast-Drying Acrylic Enamel "equal to PPG MAE" with the paint code 14676. The spray cans are about
$22 each, but they match. You can also buy the paint in quarts."
