i got some coil overs for my 1998 200sx se. The sleeves are not wide enough to fit over the tiny bronze colored peice on the top of the strut. Can I get rid of this peice by bending cutting or grinding it off/away or would that break a hole in the strut and cause the air to leak out? I dont have funds for new struts so if i could make these work it would be great. How do the fit on the back since i know there are not struts in the rear. Will modification be needed in the rear?
