Hey Butch,
The Pioneer Platform we have is the 928 X 1426. In Australia, the model is the 42112B. Actually on my invoice it was code RH42112B. Plus there is are specific Fuso leg kits and attachment plate kits available. If you need some codes for those parts let me know. I don't know the other rack so can't comment, but so far we are happy with our rack.
I will try to upload a pic of our truck with the rack on. I should add that my truck is a 2007 FG649.
Cheers...Steve
