Congratulations V6 CDX-er! You win a free burial at sea with the woman of your choice! Lol! That is exactly what I used it for! I had effed about for so long doing one side, tyring to find the best/easiest way but still took ages (theres a surprise lol) so I stopped for a cuppa and a smoke after comlpeting that side. I was in the tool box gettin out some tools ready for the next job when I spotted that extension piece, I have never used that bit for the job it was intended for lol, I have used it to put those odd spring washers on, the petal sort if you know what I mean. Anyway, I looked at it and thought, hmmmm, I wonder...... lol! I already had the pin lined up to go through the spring cup, put the bit in a screwdriver handle, put the whole thing through the hole in the hub, pushed against the cup and turned, IT HELD! First time! Couldnt believe it lol! Checked to see if it was on, it was about halfway round in the slot, so another quick push and turn and that was it on at 90 degrees, was so amazed I did the other one straight away lol! What took nearly an hour took two minutes on this side! My tea wasnt even cold, lol! I can hear feet pattering all across the country as people rush out to try this as soon as theyve read this lol!
