DO NOT use nylock or fiber insert nuts. They will loosen over time.*Maybe two of these. Not sure how lucky you will get with hole in the front of the driveshaft lining up with the new coupling arm. Use of two of the flex couplings might either make it line up, or move the coupling arm back far enough on  the driveshaft as to allow you to drill a new hole far enough behind the existing hole as to not cause the shaft to break. I have not done this, but I think the hole for the solid pin in your current driveshaft is much farther forward than the location where the hole will need to be for the new coupling arm, and use of two flex couplings (like the later tractors with this style driveshaft) will locate that hole in a solid part of the driveshaft and not cause issues by being too close to the now unused hole for the solid pin. So you will simply need to drill a new 1/4" hole in the driveshaft and use a spirol pin to attach it.</blockquote>
