Looking for 13x7 wheels

Hi? I recieved for a gift from my mother a set of 13x7 wheels that she had found for me on e-bay last christmas. Just recently I had a break-in at the storage facility I rent from and now the wheels are gone. Does anyone know where I can find another set which in fact are very rare to find since there are no call for those type of wheels and they are no longer being made. I was so close to restoring in a customized way another 1975 Toyota Corolla until the wheels were stolen from me.
