This weekend I made a step for my 2000 TC30 similar to yours. I haven't painted it yet. I wondered about the step swinging in when I went to step on it - my arthritis makes me very stiff so I thought I might be shoving it in with my foot when I went to climb up. So I found an unused hole on the foot plate and dropped a rod down to the side corner of the step- works ok.
Great to see your post. I like your toolbox on the fender- I was wondering what to do about a tool box, and also your carry all on the back of the seat!
