WARNING for 750SS and 850SS reels if you are replacing the original collar in your handle, you will need to do a complete conversion to the new gear kit/handle parts, #KIT8N-750. See Below:
THE DIFFERENCE? The original gear required an entirely different handle pivot in order to switch between right/left hand use. The newer gear and pivot can be used for either. To tell the difference between older gears, look at the long end of the gear shaft. On the older gear, the threads for the pivot go all the way up to the lip. On the newer gear, they are around 1/4" down in the shaft. The older pivot WILL NOT fit in the newer gear, nor will the older handle collar fit on the newer pivot (the thread diameters are incompatible).
