Brandon - if the ADs had a 'body' [trim] tag [Tim should know], it would be on the firewall, which is where they are for the TF series - what Brad means is the
vin tag doesn't give any info other than the GVW & s/n, if your vin tag is missing likely a trim tag would have been removed as well .... and if you study those tags on the GM site you'll see the top one is for a 1965 truck, the CDN one is from 1979
earlier ones were simpler and didn't include any year info
