Yeah, I understand about the confusion.  I did not mean that M170’s were in production alongside the 6, just a fact that the body design was the same between the two for the period that they were in production together, with the exception, of course, of the 24 volt systems and different exterior/lighting. All in all, from my “Jeep Buyer’s Guide” that I trust entirely- the M170 were produced from 1953-1957, keeping in mind that use and re-registration of surplus vehicles could alter the year. For example..my 1950 Jeepster is a 49, but it was registered in 1950, therefore classified as a 1950. Posters tend to summarize production by including prototype vehicles and last year of sale, not just production.  Having been in the Jeep business for well over 16 years, I have found very valuable information at not only a dealership level, but from other interest groups and in the time spent restoring these babies.  As far as the real numbers for the M170 go, they began on 10/27/1953 and continued through 6/1955.  Army records show production of some (very few) having been built from 1962 through 1967.  That is where you may see production from 1953-1967…mostly true!!  The CJ6 was obviously built for the consumer market, but kept the same body and added better exterior lighting, turn signals and whatnot.  They were built from 1955 (released) to 1975.  In 1976, the CJ model line had some major changes, leaving the “Kaiser” influences behind.  New grille, hood (no notch) new windshield and hinges….tons of newness.  Anyway, hope this sheds some light!  The Jeep is still available and will be relisted closer to the spring.  Thanks, guys!
