Anyone running Crane XR700?, Seems the rotor sits too high? Options

[Kerrys914]

I installed a crane XR700 in my dizzy and the rotor seems to be sit a little high now. When you look into the bottom of the rotor you will see a molded key thang that sets into a notch in the distributor shaft. This prevents the rotor from spinning once it is pushed onto the shaft.

When I push the rotor onto the shaft it hits the black optical disc. The molded thang in the rotor really doesn't set into the notch very deeply. If I twist the rotor by hand it will pop out of the notch and spin on the shaft.

Can anyone measure the amount of shaft that extends above the optical disc for me?

Cheers
