Fits all minis except Autos and those with hardy spicer joints, has no lug on as required for rod change R/H side. Sold singly.
The Mini transmission output side cover is notorious for leaking oil, but replacing the seal doesn't help for long if the bronze bush is worn too. If the cover is warped across the gasket surface you can also forget getting the diff shimmed correctly! . These might be marked as 22G420 on the casting but they have the correct size bush and seal hole.47.3mm o/d seal-31.5mm i/d bush whereas the true 22G420 has a 50mm o/d oil seal and bush size 34.8mm
