So I have no way of verifying the VIN with the DMV and they will not give me a tag.
Actually you do. The frame partial VIN is unique to your truck. Your actual VIN was CCE142S158019. Partial VINs contain the year of assembly, the assembly plant and the unique serial number. There was only one truck built in 1972 at St. louis assembly with the unique serial number of 158019. The rest of your VIN can be derived by looking at the truck or from the model number.
The question is whether the Florida DMV will title off the frame VIN. Or if they will insist on a VIN plate.
Here is a 1972 Chevy truck VIN decoder.
Plug your partial VIN into the last half and you can see how easy it to come up with the first half.
