If you want to know all that info and more. Call GM and ask for customer service, tell them you want a "Restoration Package". They will send it to you free of charge! It has every option, color, wheel bases, serial number codes. Where your truck was made, every engineering speck. I couldn't believe it when I got it. They said it would take 4-6 weeks for shipping but it only took about 5 days.
I forgot the number but you can call any GM dealer and ask them for the 1-800 customer service number. When do you ever get something for free? Now go out there and take advantage of it.
