thank you for clarification.. see, like i said I was merely pointing in the direction i didnt know for sure myself. thanks!Thats what I meant. The top hats can be reused, or the 13 top hats will fit on the 14 springs. Its the lower spring perch on the 14+ dampers that change, which we all know about already. From what I recall, Ford changed the part number of the bearing/tophat assembly in favor for a different bearing, or something to that nature, but they still work on either spring.
