ok so i just got my KYB in today. yay but there seems to be a wierd shape on the top of the actual strut. its not just round its got a octagon shape or something?? well my question is does anyone know if my Ground Caontol CO will fit over that thing or if i will have to modify my AGX to with the coilovers??????

please help me

 

is this what you're talking about? its supposed to be there

and it will not fit over the gc coilovers you have to shave the lil octagon thing you're talking about down
