Whenever I get a classic car I run the numbers usually on the cowl tag find out int outside paint etc. I have a 1980 chevy Cheyenne k10 I know from the vin it's a 350 and was made in Janesville etc. It looks like it's orig engine as it has 56k miles on it and the air still hooked up etc nothing is missing looks stock to me. Is the engine code on the driver side toward the firewall where my 64 was? I was trying to see how matching numbers from paint to anything on this rig is. Also did they have bucket type seats with a wooden console in 80. I had a matching number 78 it was a bench seat nothing like this..
