Genuine MG-Rover knuckle joint. Racers and knowledgeable mechanics insist on this OEM component due to the heavy loading it encounters in use. Even the Unipart product is aftermarket-made these days, so only boxed MG-Rover will be to the OEM standard. If you order this part from Seven, it will be supplied in a Rover box, assuring you of a genuine product. Sold each.
Please read application notes:
As used on the fronts of all Mini variants to 1984 and rear or all cars. Starting in 1984 when 8.4” discs brakes and 12” wheels were added to all models, the front ride height was raised slightly to accommodate the bigger tire diameter. A small spacer 21A1845 was used. However, these often get left out after suspension work by accident or neglect, resulting in mismatched heights from side to side. To help prevent this, starting in 1990, the factory went to the GSV1264 knuckle joint that had the spacer built-in to avoid loss. If fitting replacement front joints to later cars (1984-on) in pairs, and you want to maintain the factory-specified ride height, always order two (2) GSV1264s. If working on one side only, you should inspect the other side to determine if the knuckle joint has the spacer fitted, and order accordingly.
If you already have and will refit the earlier knuckle joint without spacer to a later car, it can be built up to correct ride height by adding 21A1845 spacer.
Rears of all cars used the GSV1118 joint without the spacer, but sometimes the spacers are used for clearance when wide tires are used, to clear wheel arch flares, etc.
