Before the CJ-5, Willys offered the public a cheaper alternative with the taller F-head, overhead-valve engine, in the form of the 1953 Jeep CJ#CJ-3B, simply using a body with a taller hood. This was quickly turned into the "M606" jeep (mostly used for export, through 1968) by equipping it with the available heavy-duty options such as larger tires and springs, and by adding black-out lighting, olive drab paint, and a trailer hitch. After 1968, M606A2 and -A3 versions of the were created in a similar way for friendly foreign governments.
