Darrin and All: The 300L was definately available with the Sure Grip limited slip rear axle----all year long. The info I have says it was standard epuipment, but I think I will defer to 300L model year consultant Don Warnaar on that one. Sure Grip was introduced in 1958 and was an option from that year on. 1957 390HP 300C performance package included a "limited slip" differential as well. I don't think I would put too much trust in the accuracy of that book!

Per the Chrysler 300 Series Pedigree, Power and Performance since 1955 hardback book from Veloce Publishing, it states on p. 119 in the chart of 300-L options that the Sure Grip option code 596 was available March 1, 1965. Does this seem correct? Does this in fact mean Chrysler did not offer this type rear until after mid-production year? I thought Chrysler offered the sure grip for years prior on 300's? Does anyone know when the first was offered? I even thought a 300-L that I previously owned with a 10/20/64 build date had a sure grip rear and my current 300-L, I believe has sure-grip with a build date of 12/28/64? Could this just be a misprint in the book? Thanks, Darrin Bailey **************************************Check out AOL's list of 2007's hottest products.
