Hi, I have a 87GN and I'm having problems trying to figure out how can I mount the rear wheels in the front. I have the 16x8 gta rims with the dimples. I understand you put the fronts in the rear and the rears in the front also you have to use a spacer. Well I purchased two spacer for each side which gives it the space from the arm. My problem is I can't put the nut on as I would want to it will barely go on. I went to the part store in hopes of buying longer wheel studs but they couldn't find the right size. Does anyone know the right stud size or part number I need or know the process on getting them on??? I appreciate any help..
