This guide has been written to assist people in determining the authenticity of an original Australian MK2 Morris Cooper S. For the MK1 Australian Cooper S, click here. There were approximately 2,500 MK2 cooper S cars produced between 1969 and 1971, with the 1971 model sometimes referred to as the MK2.5 or MK3 in Australia, due to several modifications incorporated in the car’s design.
The MK2 Morris Cooper S, as the highest spec and lowest production Cooper S in Australia, demands significant prices in the market, and accurate identification of genuine cars is essential to any prudent purchaser. The MK2 has a number of unique features when compared to the standard Morris Mini, as well as when compared to the MK1 Cooper S and international variations of the Cooper S. There are also a number of features on the MK2 which may be a result of changeover periods from the MK1, and we have tried to outline examples of these items as accurately as possible. This guide provides a detailed outline, with associated images, to assist a prospective purchaser or owner in accurately identifying a vehicle.
Number produced: Approximately 2,500 MK2 Cooper S (2,419 according to the MK2 register) were produced. Less than 170 of the 1971 spec Cooper S are believed to be produced, making them the most rare 'series'. Note, approximately 7,500 Cooper S cars in Australia were produced in total (both MK1 and MK2).
Period of manufacture: March 1969 - July 1971

* Colours noted as 'Special Order' were generally those that were not available during the MK2 production years, but have been confirmed as appearing on many MK2 Cooper S cars on the Ausmini register.
Common two-tone combinations:
The majority of two-tone cars had a 'Crystal White' roof (or 'Zircon White' for late MK2 cars), available over most of the other body colours. There are also several cars which reportedly had a black roof (code for black yet to be confirmed).
Confirming the original paint colour on a MK2 Australian Cooper S is difficult, as the code is not listed on the ID plate, but was instead affixed as a sticker behind the brake/clutch master cylinder, or less commonly, above the chassis plate. Over time, and through restorations, most of these stickers have fallen off, making original paints difficult to confirm. See images for examples.
Chassis prefix and number:
The chassis prefix on an Australian MK2 Cooper S should read YG2S4. This will be followed by a four digit unique vehicle build number (sequential number commencing at 501).
Chassis prefix and number location:
Body Number prefix:
The correct body number prefix for an Australian MK2 Cooper S is 2/06, followed by a unique body number (sequential number commencing at 001). This is in contrast to M2/06 on the MK1 Cooper S.
Body prefix and number location:
This number may be stamped in one of two locations.
The body prefix and number should be approximately 500 less than the vehicle's unique build number (the number following the chassis prefix as described in the previous section). For example, If your body number was 800, your build number stamped into the scuttle panel / firewall should be 300. A "plus or minus 10" rule is generally applied to this, as many have found these numbers to not be precisely 500 apart in all cases, likely due to assembly line changes.
The correct prefix on an Australian MK2 Cooper S should begin with '9FXEY', followed by an engine number, usually 6 digits. The engine number is located on the top of the engine block, just above the alternator. You will see a flat area of metal, where the number is stamped into the block. Note: A small number of early MK2 cars were fitted with MK1 engines during the changeover, so this engine number may not apply in every circumstance.
Engine block casting number & 'thick flange':
All Cooper S motors (MK1 and MK2) will have 'AEG312' cast into the rear lower RHS. Again, other than a small number of early cars, the MK2 Cooper S had what was known as a 'thick flange' block, referring to a thicker area where the engine block meets the gearbox, compared to the MK1 block. The MK2 thick flange block is approximately 20mm thick (vs the MK1 10mm).
Other engine block features:
Gearbox Casting Number:
An original gearbox for the MK2 Cooper S should have "22G1128" cast into the gearbox casing. This will confirm that it is the correct 4 speed full synchromesh gearbox, as were fitted to the MK2 Cooper S (along with the Mini K and others).
Gearbox Serial Number:
The gearbox casing may (but not always) have a unique serial number stamped into it, which will specifically confirm whether it is from a MK2 Cooper S. The correct serial number for the MK2 S is "FAXE 1234", where '1234' represents the unique sequence number applied to that gearbox.
Other gearbox features:
The MK2 Cooper S (like the MK1) was fitted with 'Hardy Spicer' universal joints (see images), as opposed to the rubber knuckle joints used on other Minis of the same era. The gearbox was also 'remote change', and contained the long mechanism as shown in the images.
If you have the opportunity to inspect the internals of a gearbox, the Cooper S has several unique features. The first motion shaft should have an "s" stamped into the spigot bearing end of the shaft, and have 18 teeth (as opposed to 17 on the Mini K). Note, the "s" stamp cannot be seen whilst the box is assembled. The number stamped into the cluster gear should be "22G1040" for a MK2 Cooper S. 3.44 diff ratio of course being due to the 18 tooth pinion, and 62 tooth crown wheel.
The Australian MK2 Morris Mini Cooper S had the following mechanical features:
Several factory body modifications were made to the MK2 Cooper S which are essential for accurate identification. Some of these features are outlined below:
The following features were commonly applied to Australia MK2 Cooper S police cars. These features were requested by the state governments through 'Special Purchase Orders'. Examples of the original special order paperwork are attached in the images.

Special Purchase Order 26 details:
Note, SPO16 and 26 were also applied / incorporated with SPO41 cars.
