Not sure if this will help. We had a hard time finding the American Beauty Rims for the 99 Excella. When we were getting our axle done at Axis they sourced them for us and were found at this place.
We sourced in Canada for $256 a rim and we were abel to get them for $99.
Their site has all kinds of rims I am sure you should be able to find them - if not send them the photo and the should help.
Good Luck with your search.
