In defense of the "gals" at GM, I have to say that the lady that I spoke with was very knowledgeable, took my information and gave me details on my truck (most I already knew from the VIN cruncher on the American Classics page and with reading and a couple of discussions on this site) and was extremely pleasant to deal with in the 10 minutes I was talking with her first thing on a Monday morning. She said the package would be sent right away and be at my home in 4 - 6 weeks. She was wrong, I had it in less than 2 weeks.
My experience was very positive.
