I just got these skunkwork coilovers from my friend and they came off his 93 integra with tokico blues, and i have a 93 civic with illuminas. I put them on but i couldnt get that metal tube cover thing in the threds so i didnt put them in on the front. and in the back they dont fit either but they fit on top of the threds but i think when i drive over a bump the cover hits the threds. Am i supposed to not use those covers at all? or am i supposed to have some that fit inside it?
