Yes. CNH variation on T7 long wheelbases and Magnum. Same arm though on both. Keep bushes in stock a regular wear part and when they wear it can shock load arm. When under warranty we had them replaced too often - even had CNH service guy inspect. He suggested it was fair wear and tear until he was told the bushes were less than 14 days old. Unsurprisingly new bushes appeared very soon after. Weak design.
Weight or post knocker should be in the back, fixed holes. Topper or press or something would want to be in the front floating holes. At least that's how I have our stuff. Not had a problem and been running Lynx since 2004.
