I am not as familiar with the Panels/Suburban/Carry-Alls, as I am with the trucks, but I am not aware of any source for a rear floor mat for the Panels/Suburbans/Carry-Alls.
The front rubber floor mats are the same for the trucks, Panels and Suburbans, whether OEM, NOS or reproduction.
If a rear mat exists in the aftermarket, I am interested in knowing more about them, as well.
