Hey guys, new to the forums but second square body. I own a 1977 k10. Currently using it as a daily driver which I love. The more I drive it the more I want to restore it to its former glory. It currently has a 350/350 combo with a 203 transfer case. I started to dig into the truck this week making a list for parts to start restoring it. Upon digging into found out it originally came with a 400 small block, which got me thinking what else got swapped out or is missing. Well I found a copy of a order brochure from GM heritage and went to look at my spid codes to find it's missing. So am I sol on finding out what originally came with the truck or can I get a new decal with my option codes remade?
