Hi John and All, The Imperials wheelbase was also quite different from the Chryslers. The 55 was 130 for the standard model, and 149.5 for the Limo. In 56 they went to 133 inches with the Limo still at 149.5. In 57 through at least 66 it went back to 129 inches. After 56 pretty much no exterior or interior pieces interchanged with Chryslers. 300ly, Don ----- Original Message ----- From: Johnl <john@xxxx> To: <crossram@xxxx>; <Chrysler300@xxxxxxxxxxxxxxx>; <BKWare@xxxx> Sent: Thursday, October 31, 2002 7:58 AM Subject: Re: [Chrysler300] list of SWB, and of LWB Chryslers If you are referring to the 2 door hardtops, both 1955 & 1956 Chryslers are the same panels with exception of hole locations for trim. There is no difference in the trunk fin area. The Imperials of that era are different.In 1955 the panel behind the rear window before the trunk is longer than the Chryslers. The same applies to 1956 Imperials. Hope this clears up the confusion, John Lazenby
