While a proper comparison of truck frames could not be possible without disassembly, the frames ( the part in question ) look identical on the JLC and VL. The separate inner drive train is where the difference is obvious. One model puts the direct drive on the middle drivers and the other on the outer drivers. Otherwise, interchange of the frames appears possible. Maybe the frames will once again become available from the manufacturer once the VL warrantee comes off later this year.
