I used to have the exact same setup on my WD. Problem was, with just a u-shaped clamp, the clamp is allowed to rotate on the rockshaft, allowing the geometry of the three-point setup to change. Not to mention having bent the threaded rod ends of the top link itself. This all happened especially when using an implement in reverse, such as a scoop or blade. I recently bought a '45 which had the wishbone conversion kit. It also included a toplink bracket, made of cast iron, which had two halves and clamped onto the rockshaft. Because it clamped on, it wouldn't rotate or slide side to side on the rockshaft. It looked to be original, and I think AC did make conversion kits for its' snap coupler set-up when it became evident that the three point set-up was going to win out in the market. The part has a six digit casting number, but my dealer says it's not a part number and not available. I'm planning to buy a block of cast iron and take the above mentioned clamp type toplink bracket to my Dad's shop to copy on his bridgeport. If anybody knows where these clamp type toplink brackets are available in the aftermarket, please post. I know I have seen ones identical to mine in pictures on the internet, most recently on a WD that sold on Ebay not long ago, so they are out there. Just my two plus cents worth... Good Day!
