Has anyone tried to answer the original question?

The FFR and D&D (Turn Ten Racing) are both very high quality products with very good engineering. Each takes a departure from the original- D&D is slightly different from the original in the frame design. I notice that the D&D has vastly improved the anti-intrusion frame work for the footbox areas as did FFR with their design. The FFR design is "true to the spirit of the original" but took some substantial license with the frame design. However, it is closer to the original design than 90% of the kits out there.

Keep in mind the D&D product only comes as a roller while the FFR kit comes as a kit, ready for you to build to your exact idea of what you want. Both kits are very high quality IMHO. Depends on what you are looking for.
Personally, I lean toward the D&D due to the more original looking chassis design and body. Just my 2 cent's worth.- Bob
