I do not belive they differentiated trucks, panels and Suburbans back then most of the parts were the same and the build number told you what parts were used where.

In the case of my 46 Suburban I had a vin number but no title.

For $140.00 I got a title from Nevada with no problems which I in turn converted to a Florida title. All I had to do was send them a bill of sale and $140.00.
