I'm not sure if the 240's are "floating" or not cause I've not done mine but if they're not then you will have to screw two bolts (not sure what size but probably 8 or 10mm 1.25 or 1.50 threads) into the front face of the rotor. The hole's are located between the studs. Use lots of WD-40 or sumpthin 'cause they'll probably be rusted on. It won't hurt to take a hammer and "tap" on the face plate of the rotor while you try to screw the bolts in. And make sure that you do it evenly or else it will git in a bind. Hope this helps!
