yep all's OK.
Same thread as gearbox screws. All I did was to run a larger headed screw through 1st to cut a thread. Haven't got a tap.
Screw hasn't backed it's self out and neither have the gearbox screws.
If anyones intrested in them I should be able to get a batch cut as well as some anti-squat Shimz for those that haven't got them. There soooooooo easy to use.
You'd wonder how you managed before you had them
