Front wheel speed sensor retrofit ideas?

Here was what I was looking at: Just Sharing - MegaSquirt Hemi w/Traction Control
Looks like that might actually be a stock knuckle and spindle, but with the dust shield removed. Definitely an aftermarket rotor and caliper bracket, but maybe I'm not as far off as I thought I was going to be. I think my tiny rotor might still cause some issues, but won't really know until I dig all the way in and have a closer look. Would be a real pain to remove if I needed to though, lol.
