Tracing changes isn't quite as simple as it first seems, partly because of the number of variations required to satisfy differing safety and emission requirements around the world, and partly becauseengine and transmissioq changes are rarely cross referenced to chassis numbersA/lNs.

Priorto May 1978,Jaguarissuedchassis numbersusingthe following methodbeginingwith: RHD 2W1OO1 LHD 2W5OOO1 A BW suffixindicatesautomaticgearbox(BorgWarner),though some manualcarswere incorrectlystampedwith BW suffixes. The body number;which is locatedboth on the chassis plate and on a tag behindthe rear bumperiwas simplya methodof identifying the shellpriorto it beingbuilt up into a carand givena chassis number.Bodyand chassis numbersdo not necessarily run in a set order in relationto one another. The chassis number can be found both on the tD plateand stamped into the bracketsupporting the forward end of the right-hand engine bay bracebar. VIN (Vehicle ldentification Number) FromMay 1978the VIN can be brokendown into an accurate descriptionof a car'sspecification. In order;the characters usedare as 1-3
