The rear strut bolt was a little tougher. No nut on the backside, but there isn't enough room to get a ratchet in there due to the rear blinker. I am using OTC torx bits. They are a 2 piece design. You can use a wrench on the flats of the bit itself (shudder . . . 8mm, actually perhaps it was a 5/16" but the 8mm worked), but leaving the bit inside the socket adapter makes this easier. By applying pressure with the thumb, it is a little easier to keep the wrench on the flats of the bit.
