Jaguar E-Type Chassis, Body, Engine Numbers 1961-1971 by Richard Michael Owen

This document shows factory production data for the Jaguar E-type Series 1 model in both 3.8 and 4.2-litre configuration as well as Jaguar E-type Series 2 4.2-litre compiled by the author and Jaguar Daimler Heritage Trust. It includes details on first chassis numbers by year for right-hand drive (RHD) and left-hand drive (LHD) models, and is divided into open two-seater (OTS) and fixed-head coupes (FHC) and 2+2.

Many countries titled cars on date of import instead of date produced, including USA and Canada which were often one-year out. Many documents such as Certificate of Title, Vehicle Ownership or Registration Certificate can mismatch date of manufacture.

Furthermore the state of California added a J-Tag near the chassis tag and prefixed cars J62, J63, J64, J65, J67, J68, J69 depending on year of import. For example the above car could have been registered J651E31166 or J661E31166 in the state of California. French import cars had an additional tag mounted on the RHF firewall.

Each body type has an independent linear sequence which means the number indicated only specifies the production within a particular type. Using our example chassis tag above, car 1E31166 is the 1166th LHD FHC produced with the OTS having a separate sequence. With this system is is possible for many cars to share the same number with a different prefix.

Jaguar E-type Series 1 3.8 (15,496 produced)

• 3.8 Engine Number Prefixes:
  • First engines have prefix R starting from 1001
  • From February 1963 onwards RA prefix beginning from 1001
  • Stamping is found on the engine block near the oil filter adapter, in the valley on the cylinder head, flywheel and crankshaft.
  • Most cars were suffixed 9 for 9.0:1 compression and some rare 8.0 and 7.0 cars were produced.
• 3.8 Body Number Prefixes:
  • For the open two-seater (OTS) models, body numbers start with R.
  • For the fixed-head coupe (FHC), body numbers start with V.
  • Body numbers begin at 1001.
  • Early Cars can often have mismatched body numbers, tags and stampings that are close within the range
  • Early Cars have bonnet stamping on the RH bonnet side stiffener.
  • Body number was often hand written with a grease pen/crayon on the front engine firewall, middle or side of the bonnet, backside of the dashboard near the glovebox, under original upholstery like the boot cover, floor mats, interior trim
  • Body tags were riveted on various locations of the body before paint, including the RHF engine firewall, LHR interior trunk and behind the license plate.
• 3.8 Production Chassis Numbers:
  • Chassis number is stamped on the chassis tag also known as the commission plate and on the LH side of the engine subframe known as the picture frame near the top shock absorber mount
  • Total of 15,496 3.8 E-Types produced.
  • The following table lists the 3.8-litre starting chassis numbers for each model year:

In January 1962, E-Type production had a major body revision including a new dished floor panel also known as a heel well that was a considerable upgrade. These cars came with longer clutch and brake pedals and revised carpet. Earlier cars became known as Flat Floor with a total of 2616 flat floor cars with breakdown as as follows:

Around May/June 1962 it is important to note that Jaguar completely revisited the component level body production for all cars to ramp up production. Many sub-assembles switched suppliers, such as Pressed Steel to Abbey Panels for the FHC rear hatch. This revision started with chassis 850526/860580/877355/886092.

This large production revision outlined a specific body structure that would not change in any major capacity until 1971 with the introduction of the LWB S3 V12 model. This mid-1962 change point is when the monocoque and engine subframes were sufficiently modified for strength and passenger comfort.

E-Type floors and sills were modified and most notably, twin dished recess panels were included in the rear bulkhead behind seats. These work in conjunction with modified seat tracks that allow 1.5 inches of extra legroom.

Along with the dished rear firewall, many other areas received significant changes such as the bonnet louvres becoming integral instead of a welded insert panel, the lightweight Reynolds 531 bonnet subframe featured larger gussets and the floor section was also modified with new jacking points and sills.

During this period the FHC received entirely new rear bodywork including rear fenders, rear boot hatch, rear boot hatch glass, rear boot prop rod, tail panel, fuel filler flap and rear signal light bases. This had the negative effect of limiting the first 1,491 coupes, or 13.6% of total production to different rear boot hatch metalwork and glass. FHC bodywork changed around coupe 860478/886013:
