The complete front axle spring assembly should be the same BUT the Drag Links are different between the 47-52 and the 53-55 1st series. The 47-52 use the type with the tapered tube ends that have springs inside with ball cups and threaded end plugs. The 53-55 1st type uses the late model tie rod end style. This style uses a threaded stud permanently installed within the cast drag link arm.
Hope this helps.
