LOVE your new truck! Hey here is a link to the GM Heritage Center, someone here told me about this when I was looking for info on my 1963 C50. This will be super informative in VIN decoding, finding your truck specs, brake info, you name it. It does cover all light/med/heavy models so you have to pick through it but it’s pretty well organized
