I enjoyed both you vids. What caught my eye the most was the fitting of the links compared to the Miroku 73. The 66 setup just looks superior. That begs the question, can the links of the 66 fit the 73? I would think that for manufacturing simplicity alone, Miroku would make a link that would fit both. That may be wishful thnking. Any chance that the next time you have the side panels off, you could try to see if the length, hole diameters, hole placement were the same or not? Thanks
