Hello all, so I have a set of MM front coil overs. They are the MMCO-1 Mustang Coil-over Kit, Front, Bilstein and Yellow MM Struts, 1979-2004. They are for my 88 Fox body. Now I talked with the guys there knowing they didn't come assembled but I'm having a tough time setting them up. I'm stuck on filing down the top lip area if you will. How much did you guys file down? I'm blue collar and cant really afford to mess these up. Any help in the right direction would be great. I talked with them on the phone and they stated just file it enough for the top piece to fit properly. Sorry if I'm not explaining things well. I don't have the coil kit in front of me.
