Identifying an XT GT

Decoding the Body Prefix Number:

Prior to 1971 Ford used a dual numbering system.
They had a V.I.N. (Vehicle Identification Number) - which was the same as the engine number - stamped on the front edge of the passenger side spring tower
The body prefix and serial number - which also corresponded to the numbers stamped on the I.D plate - stamped on the passenger side front of the radiator support panel.

From January 1971 onwards, Ford went to a one number system, whereby the body prefix and serial number, as it appeared on the Compliance Plate, was the same number stamped on the engine and spring tower, (which by this time had shifted from the front, to the side facing the passenger front guard).

B – identifies the month of production (See chart below for year and month codes)
12345 – is a unique number identifying each vehicle
