Yes, I have had to point out to people what they are for but this does not explain what he describes as 'plastic bushes'. I hope to hear back from him with photos.
I had the same issue with my thornton coil over though in my case it was the F28/1 that bent. I used your same fix - a grade 8 bolt and double nuts. I also removed the coil over spring and reinstalled the original spring boxes.I used grade 8 bolts and double nuts to leave a little end play. This was after the pin through the UFM bent significantly.
Thanks Neil. I have corrected the photograph. Must get some new spectacles or better still, some new eyes.Hi Ed
Your pic' is slightly incorrect.
You've highlighted the RFM lugs, the spacers are just on the outside of the lugs, to take up the space of the spring boxes
