| Here's a small tip from Uncle Jools.
When you put your mirrors back on, ditch the standard bolts and replace them with the same size Allen bolt. Then you'll be able to crack them loose with the short end of the allen key in the bolt (so you get max leverage on the long end), then (especially if you use ball end allen keys) you'll be able to flip the key round to use the long end in the bolt and just twirl 'em out (or back in).
It's about ten times speedier and easier than a 1/4 turn each time wiv a spanner. |
