Generally
Knot cross in original design with grease nipple. The middle axle is articulated in the middle and this knuckle cross sits both front, back and in the middle. 1 car therefore requires 3 junction boxes of this model.
This knuckle only fits intermediate shafts that have knuckle locks on the inside of the yoke
You need to look at your intermediate shaft to be able to determine what locking you have on the knuckles. Unfortunately, the only way, the easiest is to check the front or center cross on your middle axle.
Then compare with the pictures of the locking ring types.
