Canada’s records fo 58 must have been much better than ours. When I have a few moments I’m going to try to find a decoder. My car body left from Fisher in Cleveland to be a v-8 but ended up a 6-cyl when it left LA. It’s numbered as a sedan delivery but has side glass. It’s paint color was “special” and only interior trim was “FWS” meaning full width seat. No rear seat. I have an extra number stamped into my vin tag C-58-80 that some have suggested it a govt. tracking number.
