INFO GUIDE: 1977 - 1978 Leyland Mini 998 LS

The Leyland Mini 998LS was available in four colours, three of which are very rare. The paint code is detailed on a large sticker which sits next to the pop riveted ADR compliance plate on the driver's side of the engine bay (see images for a better description).

The colour of the car's body paint determines the colour of the side decals, vinyl roof and wheel colour applied, as outlined in the below table:

It is rumoured that around 15 cars were produced in each of the colours Green, Silver and Gold, as a test case for the launch of the 1275LS. This however has not been formally confirmed. If anyone has information on the number of LS 998cc cars produced (and the colour breakdown), please get in contact with us. 

The trim applied to the 998 LS is relative to the vehicle's paint colour. Seats were trimmed on the front surface and back in the materials / colours as outlined below:

Blue 998 LS:  The seats of the blue 998LS were trimmed in a blue cloth (spotted pattern), with black vinyl backing. Door card inserts were also trimmed with the blue fabric inserts, and black vinyl forming the surrounding card. The blue cars had black carpet as standard. Note, there is a company that can re-do your blue seats if you need them done - click here:

Silver 998 LS: Hi-Ho Silver 998LS cars came with red velour cloth seats (corduroy style), with black vinyl backing. Black vinyl was used throughout the rest of the car, and also extended to the roof lining and pillar linings, which made the flame red seats stand out very well. (Same as 1275LS counterpart).

Gold 998 LS: Nugget Gold cars came with chocolate brown velour cloth seats (corduroy style), with a cream vinyl backing. Cream vinyl was used throughout the rest of the car, and also extended to the roof lining and pillar linings. (Same as 1275LS counterpart).

Green 998 LS: Iridium Green cars came with crème coloured cloth seats (spotted pattern like the blue LS seats), and door card inserts, with a cream vinyl backing. Cream vinyl was used throughout the rest of the car, and also extended to the roof lining and pillar linings. This gave a very nice contrast on the dark green paint.

The Leyland Mini LS had the following interior features:

• All 998 LS cars should have high backed front seats. The front seats in an LS feature a lever to rest the seat forward for rear passenger entry. These seats (despite appearing the same as the 1275 LS), have a different base (they do not have the front bar and track mechanism as the 1275 LS which allows the seat to slide forward or backward.
• Fitted with retracting inertia reel seatbelts. The rear seats had the belt tower (hump) in the middle, as opposed to the flat back seat in earlier models. The rear seat also had lap sash seatbelts, however, these were not pre tensioned / retractable.
• Triple gauge instrument cluster (rev timer, speedometer, heat/fuel).
• Park brake and brake fail warning lamps. These are always present on the top dash pad, and may also be present in the top corners of the instrument cluster in some cars. These lights were an ADR requirement for 1977 and 1978 and therefore appeared on all LS models.
• Radio/cassette in the centre of the dashboard with twin speakers. The unit applied to the 998LS differed to the single speaker unit often fitted to the later 1275 LS. Radio types seem to vary, with the most common demonstrated in the images.
• Below the radio unit, the LS instruments included two additional switches. On the left side, a foglight switch, and on the right the rear window heater switch.
• The standard steering wheel fitted to LS cars is the 'Formula GT' wheel, with aluminium spokes, leather surround and rubber centre cap. This wheel appears on the majority of cars. A similar type was also used on late mini Mokes. From what we can ascertain, other wheel options could be requested when purchasing a car, and there are several different common examples, a couple of which are provided in the images.
• A vinyl boot floor mat with hessian underlining is a standard feature for the LS, designed to open out and cover the floor of the boot as well as the bootlid once unfolded.
• A rear window demister was standard. This you can identify by the thin circuit stripes across the rear window, and connecting wires coming through small metal rings / holes in the C pillar linings on either side of the screen (see images).
• All cars were fitted with black carpet, regardless of seat trim.

The chassis prefix and number for a 998 LS should be visible in two locations:

1. Embossed on the aluminium ADR compliance plate which is pop riveted to the top of the driver's side inner mudguard (in the engine bay).
2. Stamped into the top of the radiator shroud panel on the passenger side inner mudguard (in the engine bay).

The vehicle's year model will determine its chassis prefix as outlined below:

1977 LS: 

These cars can be identified by the ADR plate which will specify “Leyland Mini LS”, followed by a 9 digit chassis prefix, and a 5 digit unique chassis number. The chassis prefix should read: 022X2S4M09. All of the cars we have on the 998 LS register (except for three) conform with this rule. The cars that don't conform were built in February 1977 (well before the official launch of the LS which followed in June). These two cars are believed to be pre-production / demo cars, which we understand was discussed in issue 15 of The Mini Experience. We now have 3 of these non-conforming cars on our register, and they had a chassis number prefix 022D2S1M09.

1978 LS: 

Identifying a 1978 LS is not the same as identifying a 1977 car, as Leyland changed their chassis code practice, which has led to some confusion. The correct prefix for a 1978 Leyland Mini 998 LS is XNFAB18Y, followed by a 6 digit unique chassis number. This is not to be confused with the 1275LS, which had a chassis prefix XNFAD18Y.

Note, a couple of the images used for the radiator shroud are from a 1275LS, and are for example purposes only, demonstrating the stamping typeface used. Examples of all prefixes are provided in the images.
