Ok, so the disks are 13.7" and I got the new set as well as the 12-point tool in 12mm.

It is a tight fit to get the bit in from the back even when turning the wheels to create some space in the back of the hub carrier. I had to heat 3 of the 4 bolts somewhat and used a 10mm shaft to break the threads.

Now I have the bearing out and I released the knuckle joint of the tension strut. I plan to take the strut off and install new bushings tomorrow.

Pics to follow.
