IHC built their own 4X4 Light Line trucks at least as far back as the 1953 model year "R" Series.
IH had a long history of building 4X4 tactical vehicles for the US Government, specifically the Navy & Marine Corps.
You might be thinking of the Ford with Marmon Herrington 4x4 conversion or the Chevy/GMC with Napco 4x4 conversion.
Napco also converted some Studebakers and some Fords.
