I had a lot of trouble getting flo-flex/deflex whatever they are called to fit mine. I had the exact same problem with the wishbone-hub bush like you. Thing is I hadnt extracted all of the old bush so the sleave was still there. I had to use washers though to make the distance up. Really wasnt happy with the feel of them, especially where the rear wishbone joins to the body (the big bush), didnt move nice when you moved the arm. Id actually been sold floflex in powerflex boxes so got a refund and fitted the real deal. Not just saying this but the difference was night and day.
