Here's a link to the A12 Registry/Playground with images of the wheel disc mounting hardware that may give you some help with reproducing on your own or by a machine shop? Also the A12 Registry site is probably one of the best places to find the hardware if it is still available or some direction where to look for it.

Maybe use the cotter pin length for sizing or the dust cap diameter??
