You are probably right, I don't have much '66 material. In '67, there was an MG60, which was a tandem with the 478 ToroFlow and the regular '67 light and medium duty cab. There was also a JJ80, which was a tandem with the 637 ToroFlow V-8 and the shorter (GMC built) cab. '66 was an odd year because it was the first year of the H/J series trucks which replaced many of the larger '60-up conventional cab trucks.
