Fits all minis except COOPER S/Autos and those with hardy spicer joints and has a lug on as required for rod change R/H side. Sold singly.

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
