The Stovebolt Site Forums The Parking Lot Panels 'N Burbs Suburban, Panel, Truck Vin info 47-53

the last 2 digits are the model designation, they're nowhere on the truck - the nearest thing is the fender spears that have the series: 3100, 3200, 3600, 3800, etc ... you can usually tell which doors a burb came with because there are two hinge mounting setups on them all and the unused ones for the 'other' setup have cover plates

the particular designation would have been on paperwork, as a dealer order or factory invoice, and the 06/16 door difference could have been done at the dealer as well as the factory .... dealer has a sale for a barn door 3106, only has a clamshell 3116 on hand - switch the doors and move it out
