Yes I still have them, I'm not sure how they are measured, I make them a loose 5/8" between the "inner jaws" of the clip, a 5/8" track would fit. They are definitely smaller than the ones on my Olympic.
I have 21 in total still attached to the reinforcing band so will only need sewing to the annex canvas.
I am located south of Brisbane, my contact No. is 0412 775 781
