Ja;
Just used some epoxy/putty( green stuff sold on tv) and just stuck it onto the the tailwheel strut, then shaped, then sanded after dry.
Then another piece of tubing for the fake shock/strut. Some ply to form the triangle part, ect.
The hard part was to fabricate the black dust cover. I found some thin latex/rubber painted it black then I used a block of balsa shaped to give me the contours that matched a side-view drawing.
