Need some help identifying the forks on this parts Husky. The parts bike is a 1973 WR450. My understanding is the WR had the round leg forks. This happens to have twin ribbed fork legs and they are 33" form axle center to the top of the tube. Are these 1974 250 mag forks? The hub in the wheel is the same size on both side, like a 125 and the front brake baking plate is smaller and the tab that mounts to the leg is different than the typical 1972-1974 CR's I have
