I have been on with a converion myself for a while now and as i had a doner mx5 most of the parts are mx5 but as in previous posts i have also used the mgf back disks as thay are a good fit and with the mx5 calipers and a slite modification to the hand brake lever there was no need to replace the original handbrake cable and the bracket is a simple box section 16 mm deep by 72mm internal size with a 4mm plate over it and apropreat holes then welded a 10mm back plate to that and hay presto bolts in to origonal location of old back plate .i have photos if any one intrested but dont know how to put them on hear.
