In my research I found an add from Cox " NEW PRODUCT NEWS" seems they sold the black IFC chassis with adaptors and a new brass clip to fit the 26D.
As I had already made a tool to reproduce the standard 16D clip when someone asked are you going to make the 26D clip with adaptors? Yes is the answer.
Here is what they look like. To keep the cost down the 2 adaptors are 3D printed in nylon and fit snugly on both ends of the 26D motor.
They are $10 for the brass clip and comes with the two adaptors, same price as the 16D clip.
More pics and history here.
