I have seen some old ones and repros on ebay, they seem to indicate the disc was held down by a large hex head bolt through the wheel retention cup, My hold down however is a larged pressed steel hand wheel topped bolt through the cup. I plan to blast and paint this for my mini, just wondering if it's an early thing, or those bolts they display is less accurate.
I would take a picture but my hold down is lost in my festiva... or at moms house at the moment, I know I have it as I had seen it a week ago quite happily
