T27 Wing mirror out of alignment

[richyrich7]

Hi I’ve knocked my electric fold back wing mirror forward while reversing, I’ve pulled it back into place but it’s not aligned properly now. I’ve tried folding them in and out a few times but it’s still not right. It’s the drivers side & I’ve lost quite a bit of vision. It’s quite a blind spot now especially on the motorway. 
Any ideas or have I buggered it and need to replace it 

Thanks
