Fits all minis except with hardy splicer except auto and has a lug on as required for rod change R/H side.
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 new side covers could save you a lot of grief; they have the lug on the side for r/h fit rod-change but fit both sides or earlier transmissions with yoke-type outputs.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
For hardy Spicer type gearboxes see 22G420
