\6 swap question

Makes sense that you can swap the input shaft, but I'd question the economics. I just rebuilt a 904 and it was over $100 for the kit and another $30 for a front band, $25 for the book, and a bunch more for the cleaning supplies, snap ring pliers, etc. If you can get away with just swapping the converter, I'd go that way. It's not overly difficult, but complex and time-consuming. But the forum is all about options, and you brought up one that certainly would work!
