Thanks for clearing that up Bill! I know the Imperial and Fifth Avenue have a longer wheelbase than the Dynasty etc but does anyone know if the wheelbase of the Fifth Avenue is the same as that of the Imperial for 1990-1993? ----- Original Message ----- From: "Bill Watson" <wwatson@xxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Thursday, December 04, 2003 4:48 AM Subject: Re: IML: The Alphabet Soup of Designations The 1990-93 Imperials were Y bodies. The Dynasty/New Yorker was the C body, while the longer wheelbase Fifth Avenue and Imperial were Y bodies. Check your VIN - car make (2nd digit) is C while the car body (5th digit) is Y. If the 6th digit is a "5', you have a Fifth Avenue. The Imperial is "6". Bill Vancouver, BC
