If it is an Outlaw aftermarket chassis are you sure that it is numbered? My chassis from N&N did not have any type of ID numbering. Some sellers stamp their own ID numbers and note them on the invoice, but many do not choose to number since the state assigns their own VIN anyway. If you don't know I would call Outlaw and ask them what their practice is - 800 763-3334. Saves lots of guess work.
