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. every engineering speck, engine specks, valve sizes, gears. It has every thing in it. 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.
