As stated earlier, no front suspension parts are shared between the C bodies and the Imperials.

Guys need to remember that not only are the bolt patterns larger but the hub diameter and center register are larger as well.

Going larger on the brakes is easier on a 69 and earlier than my 72. His car uses a separate hub and rotor. The rotor itself bolts onto the back of the hub using a 5 x 4-1/2 bolt pattern. If he can find the proper offset rotor (like the old Supra mentioned above) he can simply bolt it on and go. Naturally, this does not address the caliper. That mount will have to be fabricated.

I haven't looked into it a great deal but I did scare up a 69 front hub to check things out.
