It continued to be available on the Imperial thru 1963. I do not remember how it attached to my 300F I/P, as it has been too many years since I took it apart. Sorry I can't help on that part of the question. 300ly, Gil [Non-text portions of this message have been removed] To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm Yahoo!
