Twin Question / also Forks

I am looking to install double rotors for twin brakes on my 82 twin , I am wondering what rotors fits ? It uses the 4 bolt pattern .. are the 305 or 440 rotors the same ? also I bought a set of real nice Spectra forks ,, Has anyone ever had these apart ? I have never seen anything like this Top snap ring ? Looks like it needs pushed in to release the snap ring ,, Well anyway Thanks

Does your ftont hub have provision for a second disk? I know the stock forks don't have a place to mount a second caliper.

Got to watch the diameter of the rotor as well as the mounting bolt pattern and spacing.

I am going to use the spectra forks as they have the extra caliper mount . I had hoped to remove the chrome cover on my stock front wheel to find the other rotor mount ,, Maybe I had better look first to see if it is the same as a kz650 wheel . ( Spokes )

Spectre use the same size axle, and are the fork tubes the same length and diameter?

I bought a cheap set of Calipers from Harbor Frieght and the two fork sets are the same diameter and length .. axle size is yet to see ,, Spectra forks use a one side fill for the air so checking and filling could be a bit easier ,, I will know more when I get to doing it ,,
