Are you talking about the hex's for the end of the axle so the wheels can mount on?? I believe trinity used to make some (matt francis). Most people just replaced them with the TC3 graphite hex's since they were a little wider and then you had no clearance problems with foams.
I'd suggest looking at ebay to try and find some that might be left over. I just sold my car and I had the red aluminum ones in a baggy since i didn't use them. I could probably get you in contact with guy if you want to buy them from him...
