24mm, don't buy imperial its not the same size and if it is bloody tight you want the right size socket, and buy a single hex not a double they grip better.
24mm = .9448"15/16 is actually slightly smaller than 24mm of the top of my head 23.81mm so it actually better to use being that slight bit smaller.
Is it only the rear bushes you have to do, or the front ones as well? The front ones have to be pressed out and in!!Thanks for the info, Psyching myself to have a go at it tomorrow.
