Tuff Wheel Questions

Did the Tuff Wheel ever come factory in the '70-'71 Dart (Swinger, GTs, 340) cars? What were the factory sizes (diameter and dish depth)?
I've got a RimBlo (that needs restoration), and have just seen Grant's Tuff Wheel reproduction and started thinking. Since a restoration for my RimBlo will probably be in the neighborhood of $500-$700 maybe a repro Grant Tuff Wheel may be the wiser choice.
Opinions welcomed and encouraged (I can't afford, nor do I care about, a #s matching restoration).
