Front Spindle Kit "Width Difference?"

[olsofti]

Just finished a 2.5" drop spindle with disc brakes on a 65,and the front rotors look like they are about an inch or so wider on both sides than the rears.
I haven't measured yet but they look wider.I asked CPP when I ordered the kit and they said it would be the same as the stock width,but it sure dosen't look like it.
Do any disc spindle kits keep the stock drum to drum width? I'm afraid that the 8" Corvette rallys I was planning to use will stick out too far.
